Aim: To evaluate the optimum dose and potassium application on K uptake by green gram and its buildup/depletion in soil to overcome the production of pulses in South West part of Haryana. Methodology: A series of field experiments and on farm trials were conducted during 2012 to 2016 at the Regional Research Station, CCS HAU, Bawal and at the farmers field to study the response of green gram to potassium fertilization in coarse textured medium K status soils of southern Haryana, India. Five levels of potassium (0, 10, 20, 30 and 40 kg K2O ha-1) were evaluated in randomized block design with three replications. Results: The results of study revealed that green gram seed yield increased significantly with application of potassium at 20 kg K2O ha-1. Potassium fertilization also significantly increased total K uptake by green gram at each level of potassium application and helped in preventing the depletion of available soil K and enhanced its content in the soil. The mean K use efficiency varied from 38.30 to 54.15 per cent, being maximum with application of 20 kg K2O ha-1 (54.15 %). The mean economic data analysis revealed that benefit cost ratio also increased with potassium fertilization. Interpretation: On farm trials conducted on farmers field revealed that application of 20 kg K2O ha-1 in coarse textured low to medium potash status soils is optimum for higher yield, returns and maintenance of available K status in soil.

A field experiment was conducted at Horticulture Research Station (HRS), Dailekh, in Mid-Western hills of Nepal during 2019 and 2020, to evaluate the performance of ten potato genotypes for plant, and tuber yield characters. The potato genotypes were evaluated during spring season in a randomized complete block design with three replications. The genotypes showed highly significant difference for all the traits except tuber emergence. The mean squares for the year were also significant for all the traits except tuber emergence, stem numberplant -1 and total tuber yield. The interaction between genotypes and years did not show significant differences in all the traits except stem numberplant -1. Genotype CIP392797.22 produced more marketable yield (27.5 tha -1) and total tuber yield (30.2tha -1) than all other genotypes. The genotype CIP392797.22 is characterized as medium maturing, oval-shaped and dark red-skinned one with shallow eye depth in the tuber, and it imparted 13.2% higher marketable yield than Kufri Jyoti (24.3 tha -1). Thus, the genotype CIP392797.22 is recommended to evaluate on-farm for the verification and up-scaling among farmers at Mid-Western Nepal.

The field experiments were conducted at the Punjab Agricultural University Regional Research Station, Gurdaspur, Punjab during the year 2016-17, 2017-18 and 2018-19 to evaluate the effect of Potassium application on the yield, yield attributes, nutrient uptake and agronomic efficiency under potassium deficient soils. The results revealed that the application potassium significantly increased the branches per plant, pods per plant, grain yield, biomass yield, 1000 seed weight (g), grain K content and grain K uptake. The data on the correlation analysis indicated that the K uptake was more where grain yield and biomass yield were higher. The data on partial factor productivity revealed the application of 30 kg K2O ha-1 as the best treatment to achieve highest productivity. However, data on Agronomic Efficiency indicated that the application of 30 kg K2O ha-1 may be recommended to achieve highest lentil grain yield.

Field experiments were conducted to study the effect of establishment techniques on yield and economics of red gram [Cajanus cajan (L.)] under irrigated condition at Regional Research Station, Tamil Nadu Agricultural University, Paiyur - 635 112,Tamil Nadu, India during Kharif season of 2013-14 and 2014-15 respectively in randomized block design with four replications. The treatments are line sowing/dibbling of seeds, sowing behind the country plough, sowing in polybag and transplanting at 25 and 40 DAS, sowing in portrays and transplanting in 25 and 40 DAS. The redgram variety LRG 41 was used for study. The results revealed that, dibbling of seeds in lines recorded higher grain yield of 2351 kg ha-1, net income of Rs.99495/- and B:C ratio of 3.39. Thus, dibbling of seeds in lines recorded 6% higher over sowing in poly bag and transplanting at 25 DAS and 27% higher yield over sowing behind the country plough. Considering yield and economics, line sowing seems to better option for the farmers followed by sowing in polybags and transplanted in 25 DAS. Under transplanted situation, transplanting of seedlings at 30 DAS was more suitable where the monsoon was delayed for 30 to 45 days under rainfed situation.

The Impact

Abstract Potassium fertilization and harvest timing can both impact stand life of alfalfa (Medicago sativa L.). In the Southeast, high temperatures and humidity often influence harvest timing and fertilization. Current nutrient management and harvest recommendations are generated from research conducted in northern climates with different varieties. The objective of this trial is to determine the impact of potassium fertilization and harvest regime on stand persistence, forage yield, and quality of ‘Bulldog 805’ alfalfa in the Southeast. This study was conducted at the Coastal Plain Experiment Station in Tifton, GA, on a two-year-old stand of ‘Bulldog 805’ alfalfa planted fall 2015. Plots were randomly assigned using a split block design. Main plots were harvest treatment: bud, and 10, 30, and 50% bloom stage. Plots were subdivided to examine K fertilization at rates: 0, 67, 101, 134, and 168 kg/ha, split 3 times throughout the season. Plots were visually assessed each harvest to determine ground cover and percent bloom. Fifty shoots were collected to evaluate leaf:stem and mass:shoot ratio, and yield was determined through harvest using a Swift forage harvester. Grab samples were collected for nutritional analysis using near-infrared reflectance spectroscopy. Data was analyzed using the PROC GLIMMIX of SAS with repeated measures analysis option at a = 0.05. Leaf:stem ratio was not significant for all main effects (P > 0.46). Harvest treatment had an effect on yield, with 10% bloom greater than bud stage (1,321 kg/ha and 1,104 kg/ha, respectively; P = 0.04). Crude protein levels were the greatest in bud stage and lowest with 50% bloom (22.8% and 21.2%; P < 0.01). Total digestible nutrients were greater in bud and 10% bloom compared to 30% and 50% (65% and 63%, respectively; P < 0.01). Potassium application and harvest regime can impact alfalfa growth. Funding for this project was provided by USDA-NIFA-AFRP grant #2016-70005-25653.

Rice (Oryza sativa L.) is one of the most important food crops from which nearly one third of world's population derives its principal source of calories. The experiment was conducted to discover the impending genotypes suitable for hilly situation of Karnataka. The experimental materials were chosen or selected based on significant superiority or on par yield over the local check variety, i.e., Tunga in the AICRIP investigational trials of paddy. The chosen entries were evaluated for the three years in the station trial at the Agricultural and Horticultural Research Station, Ponnampet in randomized complete block design with two replications during 2016, 2017 and 2018 kharif seasons. Third year Multi Location Trial (MLT) was also conducted at AHRS, Ponnampet and ZAHRS, Mudigere. The pooled data across the years in the station trial revealed that the entry IET-24451 recorded the utmost grain yield (6196 kg/ha) among the entries and gave up 36 per cent increased grain yield over the Tunga and 17 per cent increased grain yield over the KPR-1. The pooled data of MLT across the locations revealed that the entry IET-25281 recorded the utmost grain yield of 6076 kg/ha with 11 per cent increased grain yield over the Tunga and 13 per cent increased grain yield over the KPR-1. The combined pooled data of station trial across the years and MLT trial across locations revealed that the entry, IET-24451 of 6135 kg/ha recorded the maximum grain yield followed by IET-25281 (5970 kg/ha) among the entries. The entry IET-24451 recorded 22 per cent increased grain yield over the Tunga and 15 per cent increased grain yield over the KPR-1, whereas the entry IET-25281 recorded 19 per cent increased grain yield over the Tunga and 12 per cent increased grain yield over the KPR-1 and both the entries IET-24451 and IET-25281 recorded the leaf and neck blast resistance reaction in the Uniform Blast Nursery Screening Pattern. Hence, the entry IET-24451 was recommended for on-farm trial due to its blast resistance trait and yield superiority across the years and the locations.

THIS STudy was aimed to induce genetic variation toward drought tolerance after treatment with EMS as a mutagen to two maize inbred lines and their single hybrid. The experiment was carried out at Abo-Ghraib Research Station, Baghdad during the spring season of 2019. The experiment included three irrigation intervals 7, 9 and 11, four concentrations of EMS (0, 50, 60, and 70 mM) and three maize genotypes distributed in three replications using randomized complete block design (RCBD) with split-split plot arrangement which included three irrigation intervals 7, 9 and 11 days occupied the main plot, while the sub plots included three maize genotypes, and four EMS concentrations which were distributed in sub-sub plots. Results were revealed significant differences among EMS treatments and irrigation interval treatments. The inbred line 5 in control treatment showed a significant increase in days for both anthesis and silking (70.11 and 71.94) days, respectively. Plants of Nahrain hybrid also showed a super performance in plant height, leaf area, and number of rows ear-1, with a mean of 154.47cm, 746.31cm2 and 17.83 row ear-1, respectively. The irrigation intervals of 9 and 11 days were significantly decreased the mean performance of genotypes, compared to the shortest irrigation interval (7 days) which had highest mean in most traits. None treated plants (0 mM EMS) had a significant effect on the performance of most studied traits, except the anthesis and silking time, which gave the highest values under the concentration 60 mM with 69.11 and 70.48 days, respectively. Hybrid plants interacted significantly with the EMS concentration of 0 mM producing the maximal means of plant height and leaf area (169.56cm and 759.78cm2 respectively). On the other hand, the hybrid was significantly interacted with the shortest irrigation interval in the mean traits of plant's height and leaf area (163.50 cm and 757 cm2, respectively). The triple interaction between hybrids, shortest irrigation interval and EMS concentration of 60 mM had significantly increased leaf area reached 769.67cm2, meanwhile the triple interaction between hybrid plants, shortest irrigation interval, and the EMS concentration of 0 mM recorded the highest value of plant yield (199.67g). It can be concluded from the current study that the genotypes differed in their response to 9 and 11 days irrigation intervals, with a negative effect of the later interval on the vegetative and yield traits of maize compared with shorter irrigation interval.

In Southern India, drought stress is a major constraint to chickpea production and yield stability. Drought tolerant index (DTI) that provides a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions utilising physiological traits. Thirty chickpea genotypes were tested in a randomized complete block design with three replications under rain fed and irrigated conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh, India during rabi, 2018-2019. The analysis of variance carried out for yield and drought tolerant traits revealed highly significant differences among the genotypes for all characters under rain fed as well as irrigated conditions. NBeG 776, NBeG 779, NBeG 868, ICCV 181606, MH 13 and MH 14 are drought tolerant. NBeG 776, NBeG 779 and NBeG 868 are suitable under both rain fed and irrigated conditions with significantly higher yields over their respective means. ICCV 181606, MH 13 and MH 14 are suitable exclusively for rain fed condition with significantly superior yields over the mean.

Background: Pod fly, Melanagromyza obtusa is one of the most obnoxious pest causing grain damage ranging from 10-80% with a monitory loss of US$ 256 million annually. Being an internal feeder, infested pods do not show any external symptoms of damage until the fully grown maggots chew the pod wall, leaving a thin papery membrane intact called as window, through which adults exit from the pod. Several field studies were conducted to determine the efficacy of insecticides for the control of pod fly. However, these findings did not find acceptability and led to partial success. Insecticides that should leave lesser residues and pose lesser environmental threat have become imperative. The present study aimed to evaluate the efficacy of certain new insecticide molecules against pod fly in pigeonpea ecosystem. Methods: Two field experiments were conducted at Regional Agricultural Research Station, Lam, Guntur during Kharif, 2012 and 2013 in a randomized block design (RBD) using pigeonpea cv. ICPL 85063 (Lakshmi) with 17 treatments including untreated control and 3 replications. Two sprays were given at 10 days interval starting from pod initiation stage. At maturity, number of pods showing pod fly damage were recorded and expressed as percentage. Grain yield was recorded and cost–benefit ratio was worked out. Result: Among different insecticides, thiacloprid 21.7 SC, followed by diafenthiuron 50 WP, flubendiamide 480 SC and dimethoate 30 EC were very effective against pod fly with more grain yield and registered highest incremental cost benefit ratio (ICBR). It was further suggested that effective insecticides may be alternated in order to avoid development of resistance to pod fly in pigeonpea.

Field experiments were conducted at Coconut Research Station, Aliyarnagar during 2016 – 2019 to assess the performance of rice-based cropping sequences for water-scarce conditions of the Parambikulam Aliyar Project Command area of Tamil Nadu. Five cropping sequences viz., rice–sesame (T1), rice–groundnut (T2), rice– sunflower (T3), rice–castor (T4) and rice–black gram (T5) were experimented adopting Randomized Block Design with each sequence replicated four times. Results revealed that compared to the other non-legume sequences experimented, the contents of KMnO4-N and organic carbon in the post harvest soil, productivity of rice and economic efficiency were higher in rice–black gram followed by rice–groundnut sequence. Rice– castor sequence recorded the highest land utilization efficiency of 76.7 % and was the lowest in rice–black gram sequence (53.4 %). Rice equivalent yield was the highest on sequential cropping with sunflower (5755 kg ha-1) followed by groundnut (5028 kg ha-1). Production efficiency was the highest in rice– groundnut (47.5 kg ha-1 day-1) followed by rice–castor (42.5 kg ha-1 day- 1) systems. Net returns and benefit-cost ratio were higher in rice–sunflower and rice–black gram sequences followed by rice–groundnut and was the lowest in rice–sesame sequence. In terms of soil fertility, system productivity and economic returns, rice–sunflower, rice–black gram and rice–groundnut systems are highly remunerative for water-scarce conditions of Parambikulam Aliyar Command Area of Tamil Nadu.
