Himachal Pradesh has various agro-climatic conditions suitable for producing a wide range of vegetable crops around the year. Sixty vegetable growers were selected from the Hamirpur district of Himachal Pradesh using a three-stage random sampling method. In the past 30 years, there was a massive reduction in cereals, pulses and oilseeds; it would be due to the introduction of vegetable crops. On average, the total area put under vegetable crops was 0.2974 and 0.3158 hectares during the summer and winter seasons, respectively, on the overall farm situation. The incidence of insect pests & diseases was the significant constraint related to production. Getting a loan from the bank was time-consuming, and lack of extension facilities were the most critical financial and institutional constraints, respectively. Training should be provided to the farmers to be aware of the latest technologies of KVKs and SAUs to overcome production constraints. For financial and institutional constraints, training camps should be held to provide knowledge about new schemes of state and centre government.

Okra (Abelmoschus esculentus L.) is an essential vegetable crop with good nutritional significance. Insect pests are the major threat for poor production of the okra crop. Thrips of vegetable crops are known to be serious pests on a wide range of fruit, vegetable, flower, and agronomic crops. The present field study was carried out to know the efficacy of different insecticides (acetamiprid 19% weightable water (ww), lambda 25% ww, colarphipare 32% ww, lambda 2.5% ww and abamectin 1.3% ww) against Thrips, Thrips tabaci (Lindeman) on okra crop during the year 2019, and observations against T. tabaci (Lindeman) were recorded after 24 hrs, 48 hrs, 72 hrs and 07 days of each spray in all the treatments. The pre-treatment count of thrips on okra was non-significant (P > 0.05); while the evaluated efficacy of different insecticides against thrips was significant (P < 0.01). It was noted that all the insecticides showed their highest efficacy after 7 days of spray and acetamiprid 19% weightable water (ww) was more efficient to combat the T. tabaci as compared to other pesticides that produced field efficacy of 73.92 and 74.91% against thrips after 7 days of 1st and 2nd spray respectively. Abamectin, 1.3% ww, was reasonably successful, yielding 53.81 and 56.66% field efficacy against T. tabaci (Lindeman) after 7 days of first and second spray. Also, moderately effective was colarphipare 32% ww, which developed field effectiveness of 56.41 and 61.49% against T. tabaci (Lindeman) after 7 days of first and second spray, respectively.

High-value vegetable crops are typically grown under irrigation to reduce production risk. For water resource planning it is essential to be able to accurately estimate water use of irrigated crops under a wide range of climatic conditions. Crop water use models provide a means to make water use and yield estimates, but need crop- and even cultivar-specific parameters. There is generally a lack of crop-specific model parameters for some important commercially grown vegetable crops, especially parameters determined over both summer and winter seasons. The experimental site used in this study was on the Steenkoppies Aquifer, a catchment under stress and an important vegetable production area in South Africa. Crop-specific growth parameters and water use for 4 selected high-value vegetable crops (beetroot, cabbage, carrots and broccoli) were measured over multiple seasons (two summers and one winter). These were used to parameterise the Soil Water Balance (SWB) generic crop growth model for both summer and winter seasons. In seasons where the same cultivar was planted, a single set of model parameters could be used to successfully simulate crop growth and water use. Results show that the amount of irrigation water required is dependent on season and rainfall, with broccoli having the lowest (1.8–2.7 kg m−3) and beetroot the highest (12.2–23.4 kg m−3) water productivity (WPFM), defined as fresh mass of marketable product per unit water consumed. The root crops had a greater harvest index (HIDM) than cabbage and broccoli. The parameters obtained expand the current database of SWB crop growth parameters for vegetables and can be used in a wide range of mechanistic simulation models to improve water management at field and catchment levels.

The study examined the impacts of changing climate on productivity of temperate fruit crops          viz., plum, pear, peach and apricot in Himachal Pradesh based on climate information and farmers’ perception. Three study sites representing different elevations viz., Shimla, Kullu and Palampur were selected to relate the chill units with temperate fruit productivity. The climate element distribution over the period in each study site revealed an increase in the mean temperature to the tune of 0.050, 0.019 and 0.046 °C per year in Shimla, Palampur and Kullu respectively in the past 3 to 4 decade. The rate of decrease of rainfall per year during winter season was -9.86 mm in Shimla, -11.1 mm in Kullu and -8.6 mm in Palampur leading to a decrease in chill accrual. The chill units calculated using the UTAH model showed a decline of more than 4.97 chill units per year during December month, 0.64 units per year in January and 3.75 units per year in February month in past 26 year period in Shimla district. The decrease of 1.73, 1.84 and 1.65 chill units every year during December, January and February months were observed at Kullu. The decrease of chill units during December to February ranged from -2.8 to -12.8 per year in Palampur were also observed. The significance of the slope of chill units was worked out using Mann-Kendall trend test which indicated no significant trend for the December month for Kullu region and January and February months at Shimla. Significant decreasing trends in chill units for January to February months for Kullu, December month for Shimla and December to February months were observed at Palampur. The indications of changes in climate have also been supported by the farmers’ perception in Kullu, Kangra and Shimla districts accounting a reduction in snowfall with an increase in temperature in past 20 to 30 years affecting the chill accumulation. The temperate fruits pear, peach, plum and apricot showed significant increase in the production at the rate of 0.172, 0.064, 0.018 and 0.018 t/ha per year during the past two and half  decade respectively. Thus, the decreasing trends in cumulative chill units due to increase in temperature and reduction in rainfall in all locations varied from sub temperate climate in mid hills to temperate in high hills did not affect the productivity of temperate fruits in Himachal Pradesh and a promising replacement for apple shifting region in the face of climate change.

The article analyzes the regional production of major agricultural crops for 2000–2018, taking into account the areas of their crops and planting, gross harvest and yield in farms of all categories and agricultural organizations. During the study period, a gradual reduction in the acreage of grain and leguminous crops in the region was revealed, with stabilization at the level of 2.7 million hectares, with a wide range of variations in gross yields and yields depending on the weather and climatic conditions of cultivation. There was a reduction in the area, a decrease in gross collections and a tendency to increase the yield of potatoes and vegetable crops in farms of all categories. Measures are proposed to optimize the acreage, increase the gross yield and productivity of the main agricultural crops in the agricultural sector of the regional agroindustrial complex.

Application of entomopathogenic fungi by inundative releases has been attempted for control of a wide range of insect pests, with generally poor results. This is largely because entomopathogens are often treated as direct substitutes for chemical insecticides and applied without an adequate knowledge of their interactions with the local environment. Humidity of greater than 90% RH has long been regarded as the a critical condition for germination and infection by the spores. With both temperature and humidity controlled, greenhouse crops offer an excellent potential for pest control using entomopathogens. The long-term maintenance of >90% RH, however, is not standard practice in greenhouse production. This study explored the possibility of improving the efficacy of the fungi by temporarily changing greenhouse humidity without adversely affecting crop growth. The study included laboratory and greenhouse trials. In laboratory trials, four humidity levels of 75%, 80%, 89%, and 97.5% RH were evaluated over a 48-h period. Three commercial products of Beauveria bassiana were evaluated (Naturalis-O, Botanigard 22 WP, and Botanigard ES). Greenhouse pests of green peach aphid, melon aphid, western flower thrips, whitefly, and two-spotted spider mite were used as target insects. The infection rate of B. bassiana was found to increase when the sprayed adult insects were exposed to higher humidity levels with the maximum infection obtained at 97.5% RH. Percent infection and difference between humidity levels, however, were formulation- and host-dependent. The highest overall control efficacy was obtained by using Botanigard ES. Botanigard ES was highly effective to adult green peach aphid, melon aphid, and greenhouse whitefly at high humidities. Effects of B. bassiana against biological control agents for greenhouse vegetable crops were also evaluated. Greenhouse trials were conducted in two adjacent greenhouse compartment with high and low humidity conditions for 48 h, respectively, for selected pest insects to valid laboratory results.

Sweetpotato (Ipomea batatas L) was one crop chosen for development in Ontario in response to demand for alternative crops to tobacco and increasing demand for nontraditional vegetables. A wide range of vegetable crops can be grown in the sandy soils on the north shore of lake Erie. In 1999, there were ≈75 acres of sweetpotatoes grown in Ontario. Lack of an early cultivar to fit a short, warm season was a factor limiting production of sweetpotatoes in southern Ontario. Over an 11–growing season period, cultivars of sweetpotato from several breeding programs in the United States were evaluated for suitability to Ontario climatic conditions. Planting to harvest date season totals for heat units, precipitation, vapor pressure deficit (VPD), potential evapotranspiration, and solar radiation were calculated. Yield was regressed on these climatic variables using multiple linear regression. Of the cultivars evaluated, `Beauregard' replaced `Jewel' as the local industry standard after one season's evaluation. Of the numbered lines evaluated, NC9317 appears suitable for commercial trials. Yields varied greatly among years, and the seasonal VPD explained the largest amount of variation in year-to-year yield. Cultivars vary in their response to seasonal VPD. Yield of `Beauregard' increased with increasing seasonal VPD while NC9317 decreased. Cultivars require ability to yield in a short season and the ability to consistently produce under a range of atmospheric VPDs dictated by interannual climatic variation.

Hibiscus cannabinus or commonly known as kenaf is a versatile plant that serves as resources for numerous manufacturing and livestock industries. Originally planted in West Africa, kenaf is now distributed in many countries including Malaysia as its fibres were proved to be an ultimate alternative resource for major industries such as automotive, paper and bio-composite. In fact, in Malaysia, due to its adaptation to wide range of climatic conditions, kenaf has potentially be chosen as a new industrial crop replacing tobacco. There have been many interests on regenerating kenaf via micropropagation as the demand for this crop has been increasing tremendously since the past decades. Hence, this study is initiated with the objective to establish in vitro propagation system of H. cannabinus. The callus induction was achieved on Murashige and Skoog (MS) media supplemented with different concentrations of benzylaminopurine (BAP). It was observed that calli were successfully induced on all the BAP concentrations tested. The optimum concentration of BAP that induced the healthiest and biggest calli was 3.0 mg/l. Shoot and root induction from the calli were attempted using MS medium supplemented with different combinations and concentrations of IBA, BA and GA3. From the seven treatments, three treatments successfully induced formation of shoot; treatment T3 (MS + 1.0 mg/l IBA + 2.5 mg/l BA), treatment T5 (MS + 0.1 mg/l IBA + 2.0 mg/l BA + 0.3 mg/l GA3) and treatment T6 (MS + 1.0 mg/l IBA + 2.5 mg/l BA + 0.3 mg/l GA3). The results obtained in this study can paved for more research on tissue culture of H. cannabinus.

Cowpea Varieties

Many smallholder farmers face crop production constraints, especially under rapidly changing climatic conditions. A survey was carried out to assess farmers’ production constraints, traits, and preferred cowpea varieties. A semi-structured questionnaire was used in a survey of Buhera District, Zimbabwe, in March and April of 2018. Women farmers dominated the survey as they were 52% of the surveyed population, while men occupied 48% of the total population. Eighty-three percent of farmers cited the shortage, unavailability, and cost of fertiliser. Sixteen per cent of farmers acknowledged that they do not have access to quality seeds, and 1% cited labour as the major constraint in cowpea production. Cowpea yield varied from 100 to 500 kg/ha. However, 48% of farmers harvested 200 kg/ha.As for abiotic factors, farmers ranked heat (86%), drought (10%), and soil fertility (4%) as the most important abiotic factors.Ninety-one percent of farmers ranked rust as the most destructive disease, while 2% ranked storage rot, 1% ranked anthracnose, and 1% ranked downy mildew. Eighty-one percent of farmers cited aphids as the main pests, while 3% ranked thrips, 3% ranked legume borers, and 2% ranked pod borers as other pests.Fifty-two percent of farmers preferred varieties that are resistant to diseases such as rust, whereas 48% were not concerned about diseases.As for qualitative traits, 50% of farmers had no specific colour preference, 32% preferred white colour, 14% preferred brown colour, 3% preferred red colour, and 1% preferred tan colour. For quantitative traits, such as grain size, pod size, plant height, and head size, the preferences of farmers varied. Ninety-nine percent of the farmers interviewed preferred cowpea varieties that are bred for drought tolerance, as Buhera District is frequented by intermittent droughts. Farmers’ experience in growing cowpeas ranged from 5 to 30 years. The top ranked accessions were CBC1, IT 18, and Chibundi Chitsvuku,while the least ranked was Kangorongondo. Identified constraints to cowpea farming included lack of education,insect pests, diseases, drought, weeds, harvesting difficulties and a lack of agriculture extension advice. The survey showed that there is a need to breed for biotic factors such as pests and diseases and abiotic factors such as drought and moisture stress.
