The experiment was conducted at the Research field of Agronomy Division, BARI, Joydebpur, Gazipur during rabi seasons of 2016-2017 and 2017-2018 to evaluate the effects of twig removal on yield and yield attributes, and extra benefit incurred due to removal of twig as a leafy vegetable in pea varieties. Treatments consisted of three varieties such as V1=Natore local, V2 = BARI Motorshuti-1 and V3= BARI Motor-1 and five twig removal variables, viz. T1= control (no removal), T2 = removal of 5 cm twig at 25 DAE, T3= removal of 7.5 cm twig at 25 DAE, T4=removal of 10 cm twig at 35 DAE, T5= removal of 12.5 cm twig at 35 DAE. Leafy vegetable yield varied among the varieties and twig removal variables. The highest leafy vegetable yield (778 and 975 kgha-1) over the years was recorded in BARI Motorshuti-1 when 12.5 cm twig removed at 35 days after emergence which was at par with BARI Motor-1 at the same cutting time and the same length. The maximum pod yield (9.15 t ha-1 and 9.52 t ha-1) was recorded in BARI    Motorshuti-1 when 5cm twig removed at 25 days after emergence (DAE), which was statistically similar to the same variety with twig removal of 7.5 cm at 25 DAE. The highest gross return (Tk. 76522.00 ha-1), gross margin (Tk.48272.00 ha-1) and BCR (2.71) was recorded in BARI Motorshuti-1 when twig removed 5 cm at 25 DAE, which was similar to the same variety with 7.5 cm twig removed at 25 DAE. The result revealed that 5-7.5 cm twig removal at 25 DAE from the tip might be a profitable technique for pea (var. BARI Motorshuti-1) production for dual purpose as vegetables and pod yield.

The experiment was conducted at the research field of Regional Horticulture Research Station, Chapai Nawabganj during 2010-11, 2011-12 and 2012-13 to find out the proper combination of fertilizer nutrients (N, P, K and S) in presence of organic manure for obtaining higher yield of mango (var. BARI Aam-1). The treatments were native nutrient i.e. control (T1), N360P80K150S50 (T2), N560P120K200S70 (T3), N760P160K250S90 (T4), N960P200K300S110 (T5), and N1100P300K500S120 i.e. farmers practice (T6) g/tree/year. In addition, 20 kg cowdung/tree was used as blanket dose. Number of fruits/tree, individual fruit weight, fruit size, stone weight, peel weight, TSS content and yield of mango varied significantly due to variations of nutrients in all the years. The highest yield and yield attributes were recorded under treatment N960P200K300S110 g/tree and it was statistically identical with N760P160K250S90 g/tree. The lowest yield was obtained from untreated control plot (native nutrient). The yield benefit for the best treatment (T5) over the control was 86% in 2010-11, 64% in 2011-12 and 73% in 2012-13. The highest gross margin (Tk 2509/tree in 2010-11, Tk 2651/tree in 2011-12 and Tk 2478/tree in 2012-13) and marginal rate of return (2375% in 2010-11, 2225% in 2011-12 and 2300% in 2012-13) was also obtained from the same treatment. Three years’ study revealed that application of N960P200K300S110 g/tree along with a blanket dose of 20 kg cowdung/tree appears to be the best treatment and economically optimum for achieving higher yield of mango in Chapai Nawabganj region.

A field experiment was conducted during the summer, 2014 at College of Agriculture, Vellayani, Kerala to evaluate the influence of irrigation levels, nitrogen stress and method of application of fertilizers on growth and yield of yard long bean. The experiment consisted of four levels of irrigation, two levels of nitrogen and two methods of application. The results indicated that daily irrigation at 10 mm depth and recommended dose of nitrogen (30 kg ha-1) recorded superior values for growth parameters viz., functional leaves per plant and leaf area index The major yield attributes like number of pods per plant and pod yield per plant and total pod yield were not influenced by levels of irrigation and nitrogen indicating that irrigation once in three days at 20 mm depth and nitrogen level of 22.5 kg ha-1 is sufficient for yard long bean. Soil and foliar application of nitrogen and potassium recorded superior growth characters, however, the yield was superior when the recommended dose of nutrients were supplied as soil application. Increasing irrigation interval to three days and imparting N stress did not result in any reduction in gross income and net income while, a higher benefit: cost ratio was noted in irrigation at wider intervals. Soil application of nutrients recorded higher gross income, net income and BCR compared to soil + foliar application.

A field experiment was conducted in the Experimental Research Farm of School of Agricultural Sciences and Rural Development (SASRD), Nagaland University during the kharif season 2018. Groundnut variety ICGS-76 was sown @ 70 kg ha-1 for 60×20 cm2 spacing. The experiment was laid in split plot design with three replications. The main plot treatments consisted of two lime levels: lime @ 0 t ha-1 and lime @ 3 t ha-1 while the sub- plot treatments consisted of five sulphur levels: sulphur @ (0 kg ha-1, 10 kg ha-1, 20 kg ha-1, 30 kg ha-1 and 40 kg ha-1 along with recommended dose of fertilizer at 20:60:40 kg N, P2O5 and K2O ha-1 respectively in the form of diammonium phosphate and murate of potash. The results showed that application of lime @ 3 t ha-1 gave higher growth and yield attributes compared to no lime and also application of sulphur @ 40 kg ha-1 gave higher growth and yield attributes compared to lower doses of sulphur though there was only slight increase in the attributes between each successive doses of sulphur. Overall application of lime and sulphur increased all the yield attributes of groundnut, where the highest number of pods plant-1, seeds pod-1, 100 kernels weight, pod yield, kernel yield and stover yield were recorded when treatment was done with lime @ 3 t ha1 and sulphur @ 40 kg ha-1.

An experiment was conducted in the research field of Pulses Research Sub-Station, BARI, Gazipur during two consecutive years of 2015-16 and 2016-17 to determine the suitable dose of potassium for achieving higher yield attributes, nodulation, nutrient concentration and yield maximization of lentil. There were 5 treatments viz. T1 = Control, T2 = 30 kg K ha-1, T3= 40 kg K ha-1, T4= 50 kg K ha-1 and T5= 60 kg K ha-1 along with the blanket dose of fertilizers of N, P, S, Zn and B @ 15, 20, 10, 2 and 1.5 kg ha-1, respectively for all treatments. The experiment was laid out in randomized complete block design (RCBD) with three replications. Results revealed that the highest seed yield (1092 kg ha-1) of lentil (mean of two years) was found in T4 followed by T5 treatment and the lowest (736 kg ha-1) was noted in K control (T1) treatment. The highest % yield increase over control (48.3%) was recorded from T4 treatment. The maximum nodulation was found in T5 followed by T4 treatment. The highest protein (26.9%), N, P, K, S, Zn and B concentrations of lentil seed were recorded in T4 treatment. Therefore, the results suggest that the appliction of 50 kg K ha-1 along with N15P20S10Zn2B1.5 kg ha-1 are optimum for achieving higher yield potential of lentil in terrace soils of Bangladesh.

A field trial was conducted at Agronomy Farm of Bangladesh Rice Research Institute to find out the effect of crop establishment method and nutrient management on yield performance of BRRI developed short-duration Aman rice var. BRRI dhan62 during July to October 2016. The trial comprised of four crop establishment methods viz., M1 = BRRI recommended puddle transplanting, M2 = System of rice intensification (SRI) method (9-days old seedling transplantation), M3 = Sprouted seed in line sowing and M4 = Sprouted seed in broadcasting and three nutrient management levels viz.,N1 = BRRI recommended nutrient management, N2 = Soil test-based nutrient management, N3 = Control. The study was conducted in a factorial Randomized Complete Block Design with three replications. The result showed that planting methods had significant effects on the yield of rice. The SRI method along with BRRI recommended fertilizer dose produced the maximum grain yield of 4.49 t ha-1 which was statistically similar with that produced in SRI method day- and soil test-based nutrient management combination. The highest gross margin (Tk. 36,308.00 ha-1) and cost benefit ratio (2.06) were observed in direct seeding of sprouted seed in line sowing method along with BRRI recommended fertilizer dose. So, direct seeding of sprouted seed in line could be a suitable planting method due to reduction of 26.0% production cost associated with seedling raising and transplanting operations.

Field irrigation experiments were conducted to assess the varietal performance and correlation of pod yield and yield attributes under irrigation at the Teaching and Research Farm, University of Maiduguri, Nigeria, during 2015 and 2016 dry seasons. The results revealed that the most outstanding for fresh pod yield per plant were okra cultivar Kwadag Y’ar gagure Salkade and, Kwadam in descending order with yield ranging from 580.38-622.67g, while the composite cultivar had the lowest value of pod yield of 428.62g over the two years. The highest mean values for number of pods per plant and number of primary branches per plant were observed for Salkade and Y’ar gagure, respectively. Highest fresh pod length and fresh pod diameter were also exhibited for Salkade and Kwadag, respectively. Genotypic coefficient of variation was higher than the phenotypic variation for all the yield contributing characters. Days to 50% flowering were positive and highly significance difference associated with plant height, number of pods per plant and fresh weight per pod. Path coefficient analysis showed that number of pods per plant exhibited positive and direct effects on pod yield across years. Indirect effect of other yield components through this character also contributed mainly towards pod yield. Therefore, plant height, days to 50% flowering, number of pods per plant, pod length, pod diameter, number of primary branches per plant and fresh weight per pod could be considered for selection and improvement for high pod yielding varieties in okra.

The field experiment was conducted at Pulses Research Centre (PRC), Ishurdi, Pabna and Regional Agricultural Research Station (RARS), Jamalpur during rabi 2012-2013 to find out the effect of seed rate and walkway for green pea production as relay cropping with transplanted Aman rice. The experiment was based on six seed rates @ 50, 60, 70, 80, 90 and 100 kg ha-1 and two walking ways viz. 15 cm wide walkway at 2 m interval over the plot and control with three replications. A local cultivar of pea, named Natore was used in this trial. Results revealed that the treatment with 100 kg seed ha-1 gave the highest pod yield of 5.13 t ha-1 and 4.98 t ha-1 at Jamalpur and Ishurdi locations, respectively which was similar to 80 (S4) and 90 (S5) kg seed ha-1.. Walkway had no significant variation in yield and yield contributing characters but it produced the higher yield over the control. Using walkway, 100 kg seed ha-1 (S6) and 15 cm walkway at 2 m interval over the plot (W1) produced the highest pod yield of 5.14 t ha-1 and 4.95 t ha-1 and fodder yield of 6.70 t ha-1 and 6.13 t ha-1 at Jamalpur and Ishurdi locations, respectively. Maximum gross margin of Tk. 1,06,040 ha-1 and Tk. 1,02,401 ha-1 was contributed by combinations of using 100 kg seed ha-1 and 15 cm walking way but maximum benefit cost ratio (BCR) of 3.40 and 3.43 were obtained from S5×W1 combination at Jamalpur and Ishurdi locations, respectively. It is concluded that pea cultivar can be successfully cultivated for green pod production through the use of 90-100 kg ha-1 seed with walkway of 15 cm wide in the plot after 2 m intervals.

The study was carried out at the farmer's field of Juri Upazilla, Maulavibazar District during 2008-2009, 2009-2010, and 2011-2012 to find out the proper combination of fertilizer nutrients that promotes better fruit yield and quality of mandarin (cv. Khashi Kamla). The treatments were Native nutrient i.e., control (TI), N150P50K150Mg30 (T2), N200P75K175Mg40 (T3), N250P100 K200Mg50 (T4), N300P125K225Mg60 (T5), and N200P75K175Mg0 (T6) g/plant/year. In addition, 20 kg cowdung/plant was used as blanket dose. Yield components, yield, and TSS content (%) of mandarin varied significantly due to variation of nutrients in all the test years. Fruit yield/plant was improved significantly with increase in NPK and Mg dose irrespective of years. Application of Mg in combination with NPK increased 17-157% mean fruit yield over magnesium control. Significantly the highest yield and yield attributes were recorded under treatment N300 P125 K225 Mg60 g/plant (T5) along with 20 kg cowdung/plant in all the years. Total soluble sugar (%) content was also maximum in trees receiving N300P125K225Mg30 g/plant. The highest gross margin and marginal rate of return were achieved by the same treatment (T5). The lowest fruit yield/plant was obtained from untreated control plot (native nutrient). Three years’ study revealed that application of N300P125K225Mg60 along with 20 kg cowdung/plant would be economically optimum for achieving higher yield and better fruit quality in mandarin grown under piedmont plain soil.

Correlation analysis provides useful information for basis of selection for trait like pod and seed y ield. Seed yield is the most economic as well as very complex character in nature because it is governed by polygene and greatly influenced by environmental factors. The estimate of genotypic correlation coefficients in general higher than their corresponding phenotypic correlations indicating strong inherent association among the traits. Pod yield in groundnut is a complex and depends upon the interplay of number of components attributes. Primary yield components of groundnut <italic>viz.</italic>, pod size, sound mature kernels, shelling percentage, 100 kernel weight, kernel yield and number of mature pods per plant showed positive correlation with each other and with pod yield. A clear picture of contribution of each component is the final expression of character would emerge through the study of correlation and causation of path concept revealing different ways in which component attributes influence the complex traits. Path coefficient analysis helps in formulating the selection criteria based on these direct and indirect effects. In order to achieve the goal of increased production by increasing the yield potential of crop, knowledge of direction and magnitude of association between various traits is essential for plant breeders.

To study the effect of nutrient management strategy on production potentiality of short duration high yielding summer irrigated groundnut variety TG 51, field experiments were conducted during summer seasons of 2011 and 2012 at Bidhan Chandra Krishi Viswavidyalaya, West Bengal. Results revealed that, application of 100 % RDF + 7.5 t/ha FYM as basal increased growth and yield attributes that led to significantly higher productivity (pod yield 3320 kg/ha) besides enrichment of soil available nutrients after harvest of the crop. Pod yield decreased with further increase in NPK fertilizer above 100% RDF. However, maximum haulm yield (3979kg/ha) was recorded with 150% RDF + 7.5t/ha FYM as basal. Maximum net return: cost ratio (3.43) was found with 100 % RDF which was closely followed by that of 100 % RDF + 7.5 t/ha FYM.
