from International Centre for Agricultural Research in the Dry Areas (ICARDA) including some advanced lines from Bangladesh Institute of Nuclear Agriculture in 2006. During Preliminary Yield Trial, the genotype LG-208 produced 18.62% and 29.47% higher seed yield than the check variety BARI Masur-5 at Ishurdi and Magura respectively. Through advanced yield trials, regional yield trials, on-station and on-farm trials from 2010-11 to 2015-16, it was found that exotic germplasm LG-208 showed better performance than check (BARI Masur-5). Genotype LG-208 had significantly highest seed setting and harvest index under 20% polyethylene glycol (PEG) induced drought and considered as the drought tolerant which showed similar performance with field trials in drought-prone areas (Chapainawabganj and Rajshahi). Based on the superior performance of exotic germplasm LG-208 line, BINA has decided with the National Seed Board (NSB) of Bangladesh to register this line as a high yielding drought tolerant lentil variety, named as Binamasur-10 in 2016.

Yield Trials

Chilli is one of the most important spices as well as cash crop in Bangladesh. This study was undertaken at Bangladesh Institute of Nuclear Agriculture (BINA) to characterize the collected germplasm morphologically and select a desirable one for commercial cultivation in Bangladesh. More than fifty chilli germplasm were collected from local and exotic sources were put into evaluation to select desirable ones for directly use as varieties or for future usage as breeding materials. Through observation trials five germplasm were selected considering their better agronomic performance. Selected germplasm was evaluated through different trials at different chilli growing areas of Bangladesh during 2018 to 2020. Recommended cultural management for chilli cultivation was followed. The germplasm, IndoCF-25 produced significantly higher yield both green chilli and dried chilli than control varieties (Binamorich-1 and BARI Morich-1) in most of the trials. Over two years of advanced yield trial and on-farm trial, IndoCF-25 produced higher yield (32.00 t ha-1) while BARImorich-1 produced (12.15 t ha-1). IndoCF-25 was produced the longest plant height (78.8 cm), higher number of fruits (78.8) compared to Binamorich-1 (52.8), longer fruit size (13.95 cm), breadth (5.32 cm) and single fruit weight (11.38 g) compared to the check varieties. IndoCF-25 was found to be moderately tolerant to anthracnose, wilting and mosaic diseases, and also showed lower insect infestation than control varieties. Results of yield trials indicated that IndoCF-25-1 was suitable for cultivation in Bangladesh. Though check variety Binamorich-1 produced the highest yield (34.05 t ha-1) among three tested genotype/varieties, due to the better pungency as well as other quantitative and qualitative performances, BINA has applied for registration of IndoCF-25-1 to the National Seed Board (NSB) of Bangladesh. Consequently, the NSB of Bangladesh registered IndoCF-25-1 as a high yielding better pungent chilli variety in 2020 as Binamorich-2 for commercial cultivation all over Bangladesh.

Abstract This paper assesses the relative advantage of drought-tolerant (DT) maize, conditional on drought severity, using an unbalanced panel of 4 years of on-farm yield trials and high-resolution precipitation data (10-day measurements at a 0.05° resolution) in Malawi, Zambia, Mozambique and Zimbabwe. Under rain-fed conditions, DT maize yield exceeds that of other varieties: 7 per cent higher yields on average and 15 per cent higher yields under moderate drought stress. While this contrasts with higher estimates measured in controlled trials, it nonetheless represents an economically significant advantage. This study further measures heterogeneity in the relative advantage conditional using conditional quantile analysis.

A total of five separate field trials were conducted at farm farmers’ field in Sylhet area during three consecutive crops seasons of 2014-15, 2015-16 and 2016-17, respectively to evaluate the yield performance of improved varieties with the existing cultivars of five vegetables at farmers' field. Each experiment was laid out in randomized complete block design with six dispersed replications. The unit plot size was 5m x 8m.The results showed that improved variety of tomato (var. BARI Tomato-14) produced higher average fruit (55.60 t ha-1) yield with the yield increase of 16.93% over control. In case of country bean, the local variety Goalgadda performed better and produced higher green pod yield (14.31 t ha-1) compared to that of BARI Sheem-6. The brinjal variety BARI Bt Begun-2 was the best yielder with an average fruit yield of 25.62 t ha-1 i.e. 107.62% increase over non-Bt as check. In case of yield trial with Capsicum, locally grown cultivar California Wonder performed better and produced comparatively higher yield (14.02 t ha-1) than var. BARI Mistimorich-1. In case of summer hyacinth bean viz., BARI Sheem-7 gave higher pod yield of 14.96 t ha-1 compared to that of the check variety (11.41 t ha-1) in researcher-managed trial.SAARC J.

Three varieties of groundnut were used to assess the drought tolerance and high yielding potential. Groundnut (Arachis hypogaea L.) is an important oil seed crop mainly grown under rainfed situation. Erratic rainfall and frequent drought during the crop growth period, groundnut yields are generally low under rainfed conditions. Drought during critical crop growth stages is crucial for loss in yield of groundnut varieties. But tolerant genotypes may give better yield due to maintenance of physiological responses that were triggered during drought. On Farm Trials was conducted by Krishi Vigyan Kendra, Hansroever campus, Perambalur district in Tamilnadu, India to assess suitable drought tolerant and high yielding groundnut variety in terms of yield, acceptability and adoption potential during rabi 2018-19 in Perambalur district, India. Three varieties of groundnut were used to assess the drought tolerance and high yielding potential viz., Dharani, Co7 and TMV 7. The study revealed that Dharani recorded higher pod yield (2402 kg ha-1), higher number of pods plant-1 (26) and optimum plant population (26.3 plants m-2) as compared to farmers practice. The groundnut variety Dharani resulted in the highest shelling percentage (75%), while the lowest was registered with TMV 7. Gross and net returns were ` 115324 and ` 66593 ha-1, respectively by cultivating Dharani as against ` 87523 and ` 41550 ha-1 in the check variety. Dharani and Co7 would be a better option forrainfed cultivation in Perambalur district.

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero University Kano (BUK) and Institute for Agricultural Research (IAR), Ahmadu Bello University, Samaru-Zaria to assess the yield potential and Biolog- ical N fixation in 15 groundnut genotypes (ICG 4729, ICGV-IS 07823, ICGV-IS 07893, ICGV-IS 07908, ICGV- SM 07539, ICGV- SM 07599, ICGV-IS 09926, ICGV-IS 09932, ICGV-IS 09992, ICGV-IS 09994, SAMNUT-21, SAMNUT-22, SAMNUT-25, KAMPALA and KWANKWAS). The groundnut genotypes and reference Maize crop (SAMMAZ 29) were planted in a randomized complete block design in three replications. N difference method was used to estimate the amount of N fixed. The parameters determined were the number of nodules, nod- ule dry weight, shoot and root dry weights, pod, and haulm yield as well as N fixation. The nodule dry weight, BNF, haulm, and pod yield were statistically significant (P<0.01) concerning genotype and location. Similarly, their interac- tion effect was also highly significant. ICGV-IS 09926 recorded the highest nod- ule dry weight of 2.07mg /plant across the locations while ICGV-IS 09932 had the highest BNF value of 140.27Kg/ha. Additionally, KAMPALA had the high- est haulm yield, while ICGV-IS 07893 had the highest pod yield across the loca- tions with a significant interaction effect. The result shows that ICGV-IS 07893 and ICGV-IS 09932, as well as ICGV-IS 09994 and SAMNUT – 22, were the best genotypes concerning BNF, haulm and pod yield in the Northern Guinea and Sudan Savannahs of Nigeria respectively with the potential for a corresponding beneficial effect.

The cotton plant (Gossypium spp.) is sensitive to numerous environmental factors. This study was aimed at predicting effects of climatic factors grouped into convenient intervals (in days) on cotton flower and boll production compared with daily observations. Two uniformity field trials using the cotton (G. barbadense L.) cv. Giza 75 were conducted in 1992 and 1993 at the Agricultural Research Center, Giza, Egypt. Randomly chosen plants were used to record daily numbers of flowers and bolls during the reproductive stage (60 days). During this period, daily air temperature, temperature magnitude, evaporation, surface soil temperature, sunshine duration, humidity, and wind speed were recorded. Data, grouped into intervals of 2, 3, 4, 5, 6, and 10 d, were correlated with cotton production variables using regression analysis. Evaporation was found to be the most important climatic variable affecting flower and boll production, followed by humidity and sunshine duration. The least important variables were surface soil temperature at 0600 and minimum air temperature. The 5-d interval was found to provide the best correlation with yield parameters. Applying appropriate cultural practices that minimize the deleterious effects of evaporation and humidity could lead to an important improvement in cotton yield in Egypt.

AbstractResearch aimed at advancing conservation farming practices is typically performed using traditional scientific approaches, which have been highly successful in increasing agricultural output and efficiency. With the current emphasis on environmental and economic sustainability of agriculture, there is a need for a more integrated approach to applied agricultural research. Participatory research helps to bring scientific methods and the integrated production needs of farmers together to develop practical, effective, and carefully tested farming methods. The strength of participatory research is in the synergism of scientists and farmers working together to design, implement, and evaluate research. The development of new technologies for farming systems large or small, conventional or organic, can be greatly enhanced through more extensive use of participatory research.

In order to broaden the genetic base of maize (Zea mays L.) germplasm, it is necessary to integrate exotic materials into adapted breeding materials. The aim of the study was to compare antioxidative systems of two adapted maize inbred lines (A and B) with exotic germplasm, Drought Tolerant Population (DTP), and their backcrosses with DTP (A1, A2 and B1, B2). The content of low-molecular weight antioxidants, proline and phenolics, as well as antioxidant capacity, detected as free radical scavenging activities against DPPH radical, were measured in maize seeds. Proline content in both, embryo and endosperm was higher in backcrosses than in inbred lines and DTP, and increased in embryo by getting higher percentage of exotic germplasm. Contrary, phenolic content and DPPH radical scavenging activity of seeds, which were higher in adapted inbred lines than in DTP, were slightly decreased in their backcrosses with DTP.

Concern for the environment has focussed attention on the need for environmentally sound, yet economically profitable, farming practices. A hairy vetch (Vicia villosa L. Roth.) organic mulch system for fresh-market tomato (Lycopersicon esculentum Mill.) production provides environmental benefits by enhancing the soil and reducing the need for fertilizer and herbicide inputs and is more profitable than conventional practices. Tomato field trials over 3 years at the Beltsville (Md.) Agricultural Research Center compared the hairy vetch mulch system with black polyethylene mulch and bare ground (no mulch). Using partial budget analysis in a farm context, the hairy vetch mulch treatment was more profitable in all years under all market and yield adjustment scenarios. The vetch mulch system also was the preferred system for a risk-averse grower, according to a safety-first criterion. The combination of environmental benefits and the economic benefits to the grower make the hairy vetch mulch system an attractive alternative for producing fresh-market tomatoes in the Mid-Atlantic and parts of northeastern United States.

Coordinated Varietal Trial (CVT) and Advanced Varietal Trial (AVT) of wheat were conducted at Regional Agricultural Research Station,Doti during the year 2012 and 2013. Microplot Yield Trial (MPYT) were conducted during the year 2013. Total 20 genotypes were includedin CVT experiment of both years. Although the difference in grain yield due to genotypes was not found significant during the year 2012, NL1144 recorded the highest grain yield (4309 kg/ha) followed by NL 1140 (4295 kg/ha) and NL 1147 (4165 kg/ha) respectively. But in the year2013, NL 1097 produced the highest grain yield (4641 kg/ha) followed by NL 1135 (4383 kg/ha) and NL 1164 (4283 kg/ha) respectively.Statistically, the difference in grain yield due to genotypes was not found significant in the year 2013. Combined analysis over years was alsocarried out. Out of 20, only 10 genotypes were included in the CVT experiment, which were found similar in both years. Genotypes NL 1097(4079 kg/ha), NL 1140 (3814 kg/ha) and NL 1093 (3773 kg/ha) were found high yielding genotypes for river basin agro-environment of farwestern hills. Statistically, effect of year in tested characters was found significant whereas treatment effect was observed non-significant.Similarly, 20 genotypes of wheat were included in AVT of wheat during the year 2012 and 2013. Out of the genotypes included in AVT duringthe year 2012, KISKADEE No.1recorded the highest grain yield (3824 kg/ha) followed by CHEWINK No. 1 (3643 kg/ha) and WK 2120 (3583kg/ha). Statistically all the tested characters except grain yield were found significantly different due to genotypes. But in the same experimentof the year 2013, WK 2412 genotype recorded the highest grain yield (4407 kg/ha) followed by WK 2411 (4329 kg/ha) and Munal-1 (4054kg/ha). Statistically the difference in grain yield and other tested characters were found significantly different. Due to dissimilarity in the testedgenotypes we could not carry-out the combined analysis over years. Total 30 genotypes were included in the MPYT experiment of the year2013. Genotype WK 2272 recorded the highest grain yield (6080 kg/ha) followed by the genotypes WK 2274 (5152 kg/ha) and WK 2278(4480 kg/ha) respectively. Statistically, the difference in grain yield and other tested characters were found significantly different due togenotypes.Int J Appl Sci Biotechnol, Vol 3(3): 417-422
