Aim: Blackgram is one of the most important pulse crops raised in several types of soil under well drained conditions. Currently, it is cultivated as monocrop , intercrop as well as rice fallow crop in southern India. When the rice fallow pulse systems are described as, the pulse crop is seeded before or after rice harvest without ploughing, the remaining soil moisture may be better used through conservation agriculture measures. It's also known as a relay crop, a no-till crop, or a residual crop.In general, the production and productivity of black gram is declining because of poor management practices . Thus, this study was undertaken rice establishment methods as a strategy to determine the availability of residual moisture on the establishment of rice fallow black gram system during the early growth stages. Place and Duration of Study: A field investigation was carried out at Agricultural College and Research Institute, Madurai (Tamil Nadu Agricultural University9o54’ N Latitude, 78o54’ E Longitude with an  altitude of 147 m above MSL), Tamil Nadu, India from September 2019 to April 2020 Methodology: To see how different seeding methods and time influence the rice fallow black gram, the factors include rice planting methods as the main plot, methods of sowing black gram on rice fallow black gram as  sub plot, and time of sowing black gram on rice fallow black gram given out in sub-sub plot treatment. Results: The treatments had the best growth qualities, growth analysis, and yield. It could be because the above-mentioned combinations had higher residual moisture content, which resulted in a higher germination percentage, better crop stand, and higher growth and yield of rice fallow black gram. Conclusion: The best management strategy is to sowing black gram in rice fallow situations with a rice fallow pulse planter at 10 days before rice harvest, under the direct seeded of rice establishment technique with drum seeder.

Rice (Oryza sativa L.) is first staple crop of Nepal. The national average yield of rice is less than its potential yield, for which poor agronomic management has been reported as the critical factor. Among various agro-management practices seedling age, seeding density and nitrogen rates significantly affect the growth and yield of rice. The lower seeding density produces the taller plant, more effective tiller, lower sterility and higher grain yield. On the other hand, seedling of older age from higher seeding density gives the lowest yield. Transplanting younger seedling with low seeding density and application of recommended dose of nitrogen gives a higher yield. This article summarizes various effects of seedling age, seeding density and nitrogen rates on plant height, number of effective tillers, number of filled grains, thousand grain weight and grain yield of rice. This information may be useful for maize growers and researchers.

Milling Yield

Establishing a uniform rice (Oryza sativa L.) stand is an important beginning to managing a rice crop and attaining high yields. Most rice management practices in the United States are timed according to rice growth stages. Non-uniform rice stands, and subsequently non-uniform growth stages, present problems for the timely application of management practices for attaining high yields. Our objective was the determination of the effects of uneven emergence on rice yield, milling yield, and yield components. Experiments were conducted in 1988 and 1989 on a Hebert silt loam (Vertic Hapludoll) at the Southeast Branch Experiment Station near Rohwer, Arkansas. Uneven emergence was simulated by delayed (18 days from emergence) interseeding of rice to achieve 0, 20, 40, 60, and 80% uneven emergence. Each experiment was planted with the cultivars Lemont (semi-dwarf) and Tebonnet (tall) and was replicated 4 times. Rice yields for the uneven emergence treatment levels were significantly less than the rice yields seeded exclusively at PD1 (planting date 1), except for the uneven emergence levels 80-20 (80% planted at PD1 and 20% planted at PD2) and 60-40 for Tebonnet, and 60-40 in 1988 for Lemont. In 1989, there was a trend for head rice yields to decrease as uneven emergence levels increased. Average panicle density and number of grains per panicle for both Lemont and Tebonnet decreased with increasing uneven emergence, indicating a failure in the typical compensatory relationship between panicle density and grain per panicle. Lemont exhibited reduced average grain weights due to uneven emergence, especially at 80-20, 60-40, and 40-60 uneven emergence levels. Harvest indices were higher for PD1 than for PD2, except at 20-80 uneven emergence level. Essentially, the later emerging rice from the second planting acted much like a weed by competing against rather than contributing to rice yields. Late interseeding to enhance poor rice stands is unlikely to produce an economic return that could be expected from an adequate initial plant stand.

Abstract Foliar nitrogen (N) application is considered an important factor affecting phenology, growth, yield, and yield components of dryland wheat (Triticum aestivum L.). A field experiment was conducted to study effects of foliar N on dryland wheat (cv. Prisabk-2004) at the Agronomy Research Farm, The University of Agriculture Peshawar, Pakistan, during winter 2010-2011. The experiment was laid out in randomized complete block design using four replications. A plot size of 3 m by 4 m, having 8 rows, 4 m long and 30 cm apart was used. A total of 80 kg N ha−1 in the form of urea was applied. Out of 80 kg N ha−1, 70 kg N ha−1 was applied to the soil at sowing time, and the remaining 10 kg N ha−1 was applied in the form of foliar spray (2% N). The required foliar N was applied in various combinations (splits) at different growth stages viz. 30, 60, 90 and 120 days after emergence (DAE). Phenological development (days to anthesis and physiological maturity) was delayed, yield components and yield increased significantly (p ≤ 0.05) with foliar N over control (water spray without N). Wheat grain yield increased to the highest level (4427 kg ha−1) when 100 % foliar N was applied (no split) at 90 DAE, followed by 4050 kg ha−1 at 120 DAE, while the control (no foliar N) resulted in the lowest grain yield (2573 kg ha−1). We concluded from this study that 2 % foliar N application in a single split either at 90 or 120 DAE could improve wheat productivity under dryland condition.

A field experiment was conducted at the farm of Tamil Nadu Agricultural University, Coimbatore during kharif season (Spring) to study the effect of eco-friendly management practices on quality characteristics of transplanted lowland rice. Rice CO(R) 48 was used as a test variety. The experiment was laid out in randomized block design (RBD) with three replications and nine treatments which are T1 –100 % N through dhaincha + balance P and K through inorganic fertilizers, T2 – 50 % N through dhaincha + balance N, P and K through inorganic fertilizers, T3 –100 % N through vermicompost + balance P & K through inorganic fertilizers, T4 –50 % N through vermicompost + balance N, P and K through inorganic fertilizers, T5 –100 % NPK (150 : 50 : 50 kg ha-1) through inorganic fertilizers, T6 –100 % NPK through inorganic fertilizers + 12.5 t farmyard manure, T7 – 100 % NPK through inorganic fertilizers + 6.25 t dhaincha, T8 – 100 % NPK through inorganic fertilizers + 5 t vermicompost, T9 – Control. The results revealed that higher quality characteristics of rice including physical parameters (grain length, grain breadth and L/B ratio), chemical parameters (moisture, protein, carbohydrate, amylose, fat and fibre) and cooking quality were obtained with application of 100 % N through dhaincha + balance P & K through inorganic fertilizers followed by application of 100 % NPK through inorganic fertilizers + 6.25 t dhaincha and it was par with application of 100 per cent NPK through inorganic fertilizers + 5 t ha-1 vermicompost and 100 per cent NPK through inorganic fertilizers + 12.5 t farmyard manure. Lower quality characteristics of rice were registered in absolute control.

Frequent utilization of herbicides has caused ecological and health complications for human beings as well as for animals. Moreover, its unwise application also developed resistance in some weed species against the herbicides. Therefore, a field investigation was planned to assess the effect of multi-approached weed suppression in wheat at Reclamation Research Station, 7/3-L Ahmad Pur Sial District Jhang during Rabi 2019-20. Experimental treatment was comprised of two wheat cultivars i.e. Ujala 2016 and Faisalabad 2008 and seven weeds control approaches i.e. hand weeding, organic mulching, eucalyptus extract, neem extract, clodinafop, bromoxynil + MCPA and clodinafop + bromoxynil + MCPA including control. Results of the experiment showed that hand weedings, combined application of clodinafop + bromoxynil + MCPA and mulching significantly reduced the weeds density, fresh and dry weight of weeds. However, covering the soil surface with the organic mulch may have a great impact on the growth and yield-contributing attributes, hence produced maximum grain yield.
