Background: Groundnut is one of the most important oilseed crops of Odisha and grown in both in kharif and rabi-summer seasons. Because of excessive vegetative growth in kharif season, the yield potential is lower than rabi-summer resulting in low yield. Keeping this in view, an experiment was set up to investigate the effect of different concentration and time of paclobutrazol application on growth and yield of groundnut.Methods: A field experiment was conducted during kharif 2016 to 2018 at AICRP on Groundnut Research Farm, OUAT, Bhubaneswar, Odisha. The experiment was laid out in split plot design with different concentration of paclobutrazol in main plot and time of application in sub plot and replicated thrice. Recommended dose of 20:40:40 kg of N, P2O5 and K2O entirely applied as basal. Yield and yield attributing characters were taken at the time of harvest.Conclusion: Application of paclobutrazol at different concentration significantly reduced groundnut plant height and significant reduction was observed with application at 30 DAE. Among various yield attributing characters; pod/plant and pod yield increased significantly (24.6% and 27.4%, respectively) with application of paclobutrazol @ 100 ppm with higher benefit cost ratio of 1.97 and upto (8.4% and 17.5%) with application at 30 DAE.

A field experiment was carried out to study the effects of inorganic nitrogenous fertilizer and organic cowdung manure on growth and yield of carrot. Three different levels of urea along with three different levels of cowdung were employed in the investigation following randomized complete block design. The result revealed that the application of 150 kg N ha-1 as urea was found suitable for maximum gross and marketable yield (47.35 t ha-1 and 39.0 t ha-1, respectively), while 15 t cowdung ha-1 showed better gross and marketable yield (38.13 t ha-1 and 30.42 t ha-1 , respectively). Regarding the combined effect, the combination of 150 kg N ha-1 and 15 t cowdung ha-1 resulted in the best performance in gross and marketable yields (51.22 t ha-1 and 43.41 t ha-1, respectively). The net return (TK. 211142 ha-1) and benefit cost ratio (4.61) were maximum in the treatment combination of 150 kg N ha-1 in the form of urea and 15 t cowdung ha-1.DOI: http://dx.doi.org/10.3329/jbau.v10i1.12012J.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

AbstractA field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea var. gongylodes) at Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna from November 2014 to February 2015. The single factor experiment comprised of different types of fertilizers and manures viz., T0 (Control), T1 (Recommended doses of NPK), T2 (Cow dung), T3 (Vermicompost), T4 (Poultry manure), T5 (50 % Cow dung + 50 % NPK), T6 (50% Vermicompost + 50% Cow dung), T7 (50% Vermicompost + 50 % Poultry manure) and T8 (25% Cow dung+ 25% Vermicompost+ 25% Poultry manure + 25% NPK). The Experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The maximum plant height was obtained from the treatment T1 at 25, 35 and 45 Days after transplanting (DAT). The maximum spread of canopy was 36.75 cm, 52.50 cm and 66.05 cm from the treatment T3, T7 and T2, respectively. The maximum economic yield (21.92 t/ha) and biological yield (40.083 t/ha) were found in the treatment T1 and T7, respectively. Highest benefit cost ratio (3.07) was obtained from the treatment T1whilethe minimum (0.57) was obtained from T3 which indicates that high cost of vermicompost affect net return severely. Although, T1 produced maximum benefit cost ratio, the treatment T4 and T2 are very close to T1 and also statistically similar. So, we can consider poultry manure and cow dung for our soil health, environmental benefits and ecological safety.

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.

Government of Nepal has announced a super-zone of banana in Chitwan district and a block in Nawalparasi East district to enhance productivity and commercialization of banana subsector in the Hetauda-Dumkibas road corridor. This study is the first of its kind to analyze the competitive position of banana value chains in the corridor. Using the literature review approach, the paper generated a conceptual framework to assess competitiveness of value chain. A total of 160 producers, 22 traders, 3 wholesale commission agents and 10 agrovets were selected using stratified random sampling method. The pretested semi-structured questionnaires surveys, focused group discussions and key informant interviews were conducted to collect primary data and analyzed using STATA and MS Excel. The study revealed two value chain streams in the corridor- one in Chitwan district and another in Nawalparasi East district. Most of the structure indicators were found similar for both value chain streams. Banana market was monopolistically competitive along both chains. Producers of Chitwan district were more competitive than Nawalparasi East because of their higher benefit cost ratio and higher farm gate price for fingers. The reasons for this were relatively better institutional set up contributing to extension, insurance and training services, and better technological adoption rate in Chitwan district. In addition, the chain stream of Nawalparasi East had relatively lower marketing cost and higher market margin, market efficiency and value addition. The reasons for this were shorter chains and low level of transportation cost. Thus, policy efforts to strengthen local institutions providing extension, training, insurances, market information and credits are recommended to improve the performance of the value chain. In addition, encouraging processing and value addition of bananas should be of concern to development practitioners and policy makers.

The objective of this study was to verify levels of shade and doses of earthworm humus in the production of Lactuca canadensis L. seedlings.  The experimental design was completely randomized in a 4 x 5 factorial scheme (four levels of shade and five doses of humus).  The different levels were obtained using black polyethylene screen with 35, 50 and 70% shade and in full sun. The substrates were obtained by mixing commercial substrate for vegetables (Vivatto Slim ® plus), with earthworm humus in the proportions of 0, 15, 30, 45 and 60%.  There was no seedlings emergence in the full sun and, the treatment with 50% of shade allows the best development. The substrate without humus and with 60% presented superior results but the higher dose stood out for number of leaves (3.14) and chlorophyll content (32.9%), in 50% of shade. For the other variables, there was no difference between the commercial substrate and 60% of humus, so the commercial substrate can be used in the production of Lactuca canadensis L. seedlings, considering the ratio benefit/cost ratio.

This research was aimed at evaluating the effect of mixing substrates on the growth and yield of Oyster mushrooms (Pleurotus ostreatus). Seven substrates, namely, Trt1 (cotton waste), Trt2 (wheat straw), Trt3 (crushed baobab fruit shells, 100%), Trt4 (cotton husk + wheat straw + crushed baobab fruit shells, 1 : 1 : 1), Trt5 (baobab fruit shells + cotton husks, 1 : 1), Trt6 (baobab fruit shells + wheat straw, 1 : 1), and Trt7 (cotton waste + wheat straw, 1 : 1) were used. Each treatment was replicated 5 times and laid out in a CRD. The duration of developmental stages, yield, and biological efficiency was recorded. Cotton waste demonstrated a significantly ( p < 0.05 ) higher mycelial colonization rate taking an average of 18.20 days to complete full spawn run, 23.20 days from spawning to pinhead formation, 2.80 days for pins to mature, and an average of 26.00 days to first harvest. There was a significant ( p < 0.05 ) difference in the total number of pins with cotton waste being the highest with an average of 29.80 pins, although it was not significantly different from Trt4. The highest (5.40 cm) stipe girth was recorded from Trt4 while the highest (5.22 cm) cap diameter was recorded in Trt1. There was a significant ( p < 0.05 ) difference in yield and biological efficiency. Trt1 had the highest (1.292 kg) average yield; however, it was not significantly ( p > 0.05 ) different from that of Trt4 (1.289 kg). From the research, it was observed that mixing substrate can help to increase yield and, as a result, a higher benefit-cost ratio. Therefore, further studies should be done to evaluate the effects of mixing other substrates besides the ones used in this current research.

A pot experiment was designed for two consecutive years of (2018 and 2019) to investigate the effect of optimal use of potassium fertilizer by applying at different rates 0, 10, 20, 30, 40, and 50 mg K kg-1 10 kg pot-1 soil. Rice cv. HUR-36 (Malaviya Dhan-36)] crop was transplanted by maintaining four seedlings in each pot and potassium fertilization effect on plant growth and yield attributes of rice was recorded. The experiment was carried out in completely randomized design (CRD) with seven treatments viz., T1: absolute control (0:0:0), T2: 60:30:0 mg kg-1, T3: 60:30:10 mg kg-1, T4: 60:30:20 mg kg-1, T5: 60:30:30 mg kg-1, T6: 60:30:40 mg kg-1 and T6: 60:30:50 mg kg-1 corresponding to 120, 60, 60 (N:P2O5: K2O) kg ha-1. The experiment was conducted in triplicate. The data pertaining to experiment revealed that plant height, effective no. of tillers, chlorophyll content and grain and straw yield were significantly increased as the scheduled rates of potassium fertilizer application increases. In treatment T5 receiving 60:30:30 mg kg-1, potassium was general recommendation but due to intensive cropping of rice, mining of K was noticed. Therefore, increased dose of potassium should be recommended to maintain the replenishment of K in soil system and other side benefit cost ratio should not affect negatively. The treatment received extra doses of T6 to T7 (60:30:50 mg kg-1) showed highest growth in plant and yield of rice but in steady state which is not beneficial economically. Hence, in T7 benefit cost ratio will be poor. In the present experiment, T6 maintains all fulfillment of K whether in plant or soil system.
