A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

The suitability of crop varieties in a particular location determines the productivity of crops. A field experiment was conducted from February to May 2020 at Shankharapur, Kathmandu, Nepal to evaluate the growth and productivity of potato varieties with and without mulch. Five potato varieties (Cardinal, Janakdev, Khumal Bikas, MS- 42.3, Panauti Local) were evaluated under straw-mulch and no-mulch conditions. The treatments were arranged in two factorial Randomized Complete Block Design (RCBD) with 3 replications. The results revealed that the highest tuber yield was produced by Janakdev (34.29 t ha-1) followed by Panauti Local (29.52 t ha-1). Similarly, straw-mulch gave higher yield (25.9 t ha-1) as compared with no mulch condition (21.73 t ha-1). The higher tuber yield in the Janakdev and Panauti Local was because of higher tuber weight per hill, higher number and weight of medium size (50 -100 g) and oversize (> 100 g) tuber per hill. Similarly, higher yield in straw mulch was due to higher number and weight of tuber per hill. Higher gross return, net return was observed and the benefit cost ratioin varieties Janakdev (4.08) and Panauti Local (3.53) and rice straw mulch (2.88). Therefore, potato varieties Janakdev and Panauti Local with straw mulch are most suitable for Kathmandu like climate for improving productivity and profitability.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh for 2 consecutive years during 2006-07 and 2007-08. The objective was to find out the optimum nutrient management practice on leaf area index of each component crop of potato-mungbean-T. Aman rice cropping pattern. Twelve nutrient management treatments were tested in RCBD with 3 replications. Treatments combination based on cropping pattern were T1=HYG (0-198-44- 194-24-6-1.2 for potato; 0-24-40-48-24-3-1.2 for mungbean ; 0-80-16-44-12-2-0 for T.Aman rice ), T2=MYG (0-140-34-138-18-4.5-0.9 for potato; 0-20-36-40- 20-2-1 for mungbean ; 0-56-12-32-8-1.5-0 for T.Aman rice), T3=IPNS (10000- 168-38-170-18-6-1.2 for potato ; 5000-9-37-36-21-3-1.2 for mungbean ; 5000- 65-13-32-9-2-0 for T.Aman rice), T4=STB (0-171-40-164-22-5-1 for potato; 0- 20-36-40-22-2-1 for mungbean ; 0-68-15-37-11-2-0 for T.Aman rice), T5=FP (0- 97-16-91-0-0-0 for potato ; 0-6-5-4-0-0-0 for mungbean ; 0-39-37-12-0-0-0 for T.Aman rice), T6=CON (0-0-0-0-0-0-0 for potato, mungbean and T.Aman rice) kg/ha CDNPKSZnB, T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI for potato-mungbean T.Aman rice cropping pattern, respectively. Average of two years data showed that HYG+CRI treatment gave maximum LAI followed by HYG, IPNS+CRI, IPNS, STB+CRI, and STB treatments at 60 days after planting (DAP) for potato, at 50 days after sowing (DAS) for mungbean, at 60 days after transplanting (DAT) for T.Aman rice, respectively. For potato, there was a significant (p?0.01) and positive linear relation between the LAI at 60 DAP and the tuber yield. While there was a significant (p?0.01) and positive linear relationship between the LAI at 50 DAS and seed yield of mungbean. In case of T.Aman rice, there was a significant (p?0.05) as well as positive linear relationship between the LAI at 60 DAT and the grain yield of rice.

A field experiment was conducted at Char Jangalia under MLT site, Laxmipur, a coastal district of southern Bangladesh, during Rabi season of 2015-16 to evaluate the effect of integrated nutrient management on growth and yield performance of soybean (var. Glycine max L.). Six treatment combinations, viz. T1= Control, T2= Farmers practice (25-15 Kg NP ha-1, T3= 100% recommended dose (30-25-55 Kg NP ha-1, K), T4= 50 % recommended dose + 1.5 t ha-1 vermi compost, T5= 50 % recommended dose + 5 t ha-1compost and T6=50 % recommended dose + 1.2 kg ha-1 bio fertilizer were tested. The experiment was laid out in randomized complete block design with 3 replications. There were significant differences among the different treatment combinations in terms of yield and yield contributing characters. Integrated nutrient management with application of 50% of the recommended doses of urea, TSP, MoP, and biofertilizer (Bradyrhizobium) at the rate of 1.2 kg ha-1 significantly increased most of the parameters, such as the plant height, number of nodule per plant, pods per plant, seeds per pod and seed yield. The highest seed yield (2.93 t ha-1) was recorded from T6 while the lowest seed yield (1.83 t ha-1) was obtained from T1. The highest gross return (Tk.117200 ha-1) and gross margin (Tk. 71840 ha-1) was obtained from T6, whereas the lowest gross return (Tk. 70400 ha-1) and gross margin (Tk.27880 ha-1) was obtained from T1. The overall results indicated that the application of integrated nutrient management of a combination of bio fertilizer with 50% N-P-K (15- 12.5-27.5 Kg ha-1) of the recommended dose produced the maximum nodulation and seed yield of soybean in the southern coastal char land.Bangladesh Agron.

The experiment was conducted during rabi season 2019-2020 at Agricultural Research Station, On Farm Research Division, Alamnagar, Rangpur to find out the useful effects of organic fertilizer on growth and yield of tomato. The experiment was arranged in a randomized complete block design (RCBD) with five treatments in three (03) compacted replicate blocks. The treatments included T1: 100% Recommended Chemical Fertilizer (RCF), T2: 85% CF + 3 tha-1 organic Fertilizer (OF), T3: 85% CF + 1 tha-1 OF, T4: 70% CF + 3 tha-1 OF and T5: 70% CF + 1 tha-1 OF. The highest yield was observed in T2 (50.59 t ha-1) due to more number of fruit plant-1& weight of fruit plant-1 and the lowest was in T5 (35.32 t ha-1). These results may be due the parameters of growth components increased with increasing amount of organic and inorganic fertilizers applied. Combination of organic and inorganic fertilizer treated plots produced higher yield than plots without combination of organic and inorganic fertilizer. The highest gross return (BDT. 607080) was found in T2 treatment and the lowest gross return (BDT. 423840) was recorded from T5. The highest gross margin (BDT. 328520 ha-1) was obtained from T2. The lowest gross margin (Tk. 145280 ha-1) was obtained from T5. Integrated nutrient management (combination of organic and inorganic fertilizer) is the best option for higher tomato production in Bangladesh. Progressive Agriculture 32 (1): 10-16, 2021

Potato (Solanum tuberosum L.) is a versatile crop and a source of inexpensive energy in the human diet in many countries. It can be used as fresh products and commercially processed foods such as French fries and chips. Potato varieties development research previously conducted in Ethiopia related to processing quality were limited in their scope of quality parameters. This experiment was conducted at Holetta Agricultural Research Centre, Ethiopia during the main crop season of 2017. Twenty-four potato genotypes were evaluated for 23 quantitative and six qualitative traits in randomized complete block design with three replications to determining the nature and magnitude of common genetic diversity and to screen out genetically diverse parents by using cluster and principal component analysis. The first eight principal components accounted for 90.26% of the observed variations among 24 potato genotypes. The first three PC accounted for 60.43% of the variation. The genetic distances among the 24 potato genotypes ranged from 3.40 to 11.80 and the genotypes were grouped into eight clusters based on quantitative and qualitative traits. Cluster II consisted of 25%, Cluster IV, I, III contained 20.83%, 16.67% and 12.5% of genotypes, respectively, while Cluster VI, VII and VIII each consisted of one genotype. In conclusion, genotypes grouped under Cluster II and VIII worth further evaluation to obtain genotypes with highest total tuber yield, the specific gravity of tuber, dry matter content, total starch content, acceptable tuber physical and frying quality with other desirable traits.

ABSTRACT The objective of this study was to evaluate the yield potential, frying quality, plant vigor, and vegetative cycle of Chilean potato clones, aiming to identify those with potential to become new cultivars or to be used in breeding programs. The experiments were conducted in Pelotas-RS and Canoinhas-SC, Brazil, in spring 2017. A set of 37 advanced potato clones belonging to the Agricultural Research Institute of Chile (INIA) was compared to commercial cultivars Agata, Asterix and Atlantic. A randomized complete block design with three replications of two rows with 10 plants each was used. Tuber yield, frying quality, plant vigor and vegetative cycle traits were evaluated. The data were submitted to analysis of variance, test for grouping means, and the selection differential. In this set of clones there are some presenting superior quality in relation to marketable tuber yield and frying quality, but the vegetative cycle was not shorter nor plant vigor was lower. Clones CH 27 and CH 44 were the best for marketable tuber yield and frying quality at both locations.
