Greengram is an important short duration pulse crop grown extensively throughout India. The productivity is very less when compared to other pulse crops in India and in Uttar Pradesh. Hence, the experiment was conducted with the aim of identifying different genotypes and characters that will be useful in improving its productivity. The present investigation was intended to study the extent of variation, heritability and genetic advance among different characters of greengram in sandy loam soils of Uttar Pradesh in a set of 20 genotypes including check Samrat in randomized block design with three replications during the Kharif, 2017. Observations were recorded for 13 quantitative characters. The genotypes KM11 584, KM11 583, RMG 1030, MH 934, NAVYA and SHARIF were identified as desirable genotypes. Harvest index, biological yield per plant, number of clusters per plant, number of seeds per pod exhibited high GCV, PCV, heritability and genetic advance as percent of mean. Thus priority should be given to these characters during selection in breeding programme for greengram yield improvement.

To know the expression of diversity, their extent and pattern, field evaluations of 119 indigenously collected wheat germplasm were conducted under temperate valley conditions at KD Research Farm of NBPGR, Regional Station Jammu and Kashmir, India, for two consecutive years. All together 14 traits were undertaken. To measure the diversity simple statistical tools like maximum, minimum and standard deviation were taken into account. Correlation study, principal component analysis and cluster analysis were performed. Excellent amount of diversity were expressed by the tested germplasms. Standard deviation showed highest variation in yield deciding factors, i.e., the biomass and gain yield. Correlation studies accord that no. of spikelets / spike had maximum influence with other traits of Kashmir Valley conditions. PCA bi-plot study showed less variation as compare to other traits. Cluster analysis suggested that plant height was significantly correlated with all the traits except no. of spikelets / spike. Excellent amount of diversity were expressed under temperate Kashmir valley conditions by the all the tested wheat germplasms various traits, which can be utilised as donor in the temperate wheat breeding program.

Data from 1991 to 2017, pertaining to early performance traits was collected from 659 Murrah buffaloes, sired by 188 bulls, maintained at Directorate of Livestock Farms, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, Punjab. Least squares means and effect on non-genetic factors were evaluated for economic traits. Moderate heritability estimates of 0.217 ± 0.00, 0.231 ± 0.00, 0.260 ± 0.046 were calculated for first calving interval (FCI), First 305 day milk yield (F305MY) and first peak yield (FPY) respectively and low heritability values of 0.015± 0.025 and 0.043 ± 0.03 were estimated for age at first calving (AFC) and first lactation length (FLL) respectively. The phenotypic and genetic correlation of AFC was found to be positive with FLL and FCI and negative with F305MY and FPY. Although the production efficiency traits like F305MY, FLL and FPY had high positive genetic and phenotypic correlation among themselves.

Phosphorus (P) is an important element that is applied in the form of di-ammonium phosphate or single super phosphate in potatoes. An experiment was conducted at ICAR-Central Potato Research Station, Patna, Bihar during Rabi, 2017-18 and 2018-19 to evaluate invariably use of phosphorus fertilizers in potato crop. The use of phosphorus is often applied at higher rate than its uptake from the soil. Therefore, experiment was undertaken with the objective to optimize and utilize soil phosphorus more efficiently. Potato variety Kufri Khyati was planted in three replications with eight different treatments of fertilizer phosphorus. Data on tuber yield (t/ha) and tuber number (lacs/ha) was recorded. The maximum tubers were recorded at 20% of recommended dose of phosphorus i.e. 5.14 lacs/ha followed by 100% recommended dose of phosphorus (4.56 lacs/ha). The tuber yield was maximum at 100% recommended dose of phosphorus (33.53 t/ha) followed by 50% recommended dose of phosphorus (31.35 t/ha), which was at par with the yield obtained at 20% (30.29 t/ha) to 40% (29.98 t/ha) of recommended dose of phosphorus. The recorded results showed that the omission of phosphorus does not have any significant reduction in the yield as compare to tuber numbers. Therefore it may be recommended that in high P soils, the maintenance dose of 20 % of recommended dose of P is sufficient to harvest economic yield.

Yellow stem borer (YSB) is one of the most serious and monophagous pest of paddy in India. Field experiments were carried out to assess the different management modules against the yellow stem borer in paddy during the Kharif season of 2019 and 2020. The results on efficacy of modules revealed that during both the years the minimum ‘Dead Heart’ (DH) (10.1 and 11.4% during the year 2019 and 2020, respectively) was recorded in M3 (clipping of terminal shoots at the time of transplanting and application of cartap hydrochloride 50 SP) followed by M2 (11.9 and 14.5% during the year 2019 and 2020, respectively) in which 1st application was done with fipronil 0.3G and 2nd with NSKE 5% and M1 (19.6 and 20.9% during the year 2019 and 2020, respectively) i.e. farmers’ practice where only carbofuran 3G was applied. ‘White Ear Head’ (WEH) was also recorded minimum in M3 (11.6 and 12.1% in the year 2019 and 2020, respectively) followed by M2 (13.3 and 16.4% in the year 2019 and 2020, respectively) and M1 (20.8 and 22.4% in the year 2019 and 2020, respectively) in paddy. Maximum yield (33.8 and 43.1 q/ha during the year 2019 and 2020, respectively) was also recorded in Module 3 practiced clipping of terminal shoots and spraying with cartap hydrochloride 50 SP with the highest BC(Benefit: Cost) ratio 1.52:1 and 1.94:1 in the year 2019 and 2020, respectively. The overall results of the present study indicating the overall superiority of M3 (clipping of terminal shoots at the time of transplanting and two applications of cartap hydrochloride 50 SP at 40 and 60 DAT) in all the aspects i.e. DH, WEH, yield and BC ratio.

An online survey was performed among the different categories of farm households in Nagaon district, Assam. Out of 300 cropped based agricultural farm households, of farmers were selected randomly and were grouped in accordance to their operational holdings viz. marginal (<1 ha), Small (1.01 to 2 ha), Medium (2.01 to 4 ha) and large (>4.01 ha). The necessary information was collected through their Whatsapps, messages and telephonic conversation from different 43 revenue villages. With a view to estimate the loss of crops cultivated during Lockdown Period (24th March, 2020 to 18th April, 2020) due to COVID 19 and determines the loss percentage of different crop enterprises for each group of farmers with district as a whole. After analyzing the received information it was found that large farms suffered maximum (71.69%) due to small tea garden and betel vine and medium farms incurred loss of about 61.33%. the overall loss of crops was 68.96% . The loss was found to be chiefly due to acute shortage of field labourers following COVID 19 restrictions during Lock Down period 1. As a result of which plucking, harvesting, marketing etc. all are at halt.

A field experiment was conducted during two consecutive years of 2015-16 and 2016-17 at Central Potato Research Station, Patna with objective to evaluate theresponse of zinc on potato tuber yield. Significant effect of zinc application was not noticed on plant emergence and plant height of crop at 30 days after planting. However, higher plant height was recorded in the plot which received the zinc as compare to without zinc application. Significant difference in plant height was observed at later stages of crop due to application of zinc at the rate of 6.0 kg/ha along with recommended dose of fertilizers. Similarly, dry matter yield of potato tubers was also recorded consequently higher due to application of higher doses of zinc. Tuber grades of 0-25g and 25-50g were found non-significant irrespective of doses of zinc application in potato. Significant variation in medium and large size tuber yield were recorded due to application of zinc @ 6 kg/ha over without zinc application. About 18.1% increase in marketable tuber yield of potato was found due to application of zinc @ 6.0 kg/ha as compare to without zinc application. About11.3% and 13.7% increase in the total tuber yield of potato was observed due to application of zinc @ 4.5 and 6.0 kg/ha, respectively over without zinc application. However, no significant variation in pooled yield was found with application of zinc up to 3.0 kg/ha over without zinc application. The highest net return (Rs. 36.0×103/ha) and net benefit cost ratio (2.52) was recorded due to application of zinc @ 6.0 kg/ha as compare to without zinc. Application of zinc @ 6.0 kg/ha along with recommended dose of NPK may be found more beneficial for potato cultivation under Eastern Indo-Gangetic plains of India.

About11.3% and 13.7% increase in the total tuber yield of potato was observed due to application of zinc @ 4.5 and 6.0 kg/ha, respectively over without zinc application. However, no significant variation in pooled yield was found with application of zinc up to 3.0 kg/ha over without zinc application. The highest net return (Rs. 36.0×103/ha) and net benefit cost ratio (2.52) was recorded due to application of zinc @ 6.0 kg/ha as compare to without zinc. Application of zinc @ 6.0 kg/ha along with recommended dose of NPK may be found more beneficial for potato cultivation under Eastern Indo-Gangetic plains of India.","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89599410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two separate experiments were conducted to evaluate the suitability and effectiveness of lac mud on flower production of rose and Chrysanthemum flowers under pot culture. Lac mud is produced during primary processing of lac to a tune of about 2.5 to 4.5% on dry and wet weight basis, respectively, of the raw material processed. Lac mud was grinded in fine particles and treated with lime (@ 25 g per kg of lac mud) followed by enriching with each of N, P and K as per treatments, and azotobacter and PSB each @ 25 g/kg of lac mud. Experimental results revealed that lac mud enriched with 0.2% N + 0.2% P2O5 + 0.2% K2O produced the highest number and weight of chrysanthemum and rose flowers which was significantly superior to all other treatments, except lac mud enriched with 0.2% N + 0.2% K2O for number and weight of rose flowers. The increase in number and weight of flowers with application of lac mud enriched with 0.2% N + 0.2% P2O5 + 0.2% K2O was 47.4 and 38.5 per cent in chrysanthemum and 25.5 and 31.7 per cent in rose over conventional method of manuring (application of vermicompost), respectively. Thus, application of lac mud for manuring in floriculture may give another diversified dimension to lac processing factories along with saving of inorganic fertilizers and improvement in soil fertility status.
通过盆栽试验，评价了紫胶泥对玫瑰和菊花开花的适宜性和有效性。紫胶泥是在紫胶初级加工过程中生产的，按所加工原料的干重和湿重分别计算，其含量约为2.5至4.5%。将紫胶泥磨成细颗粒，用石灰(每公斤紫胶泥25克)处理，然后按处理方式分别添加N、P和K，并分别添加固氮菌和PSB(每公斤紫胶泥25克)。结果表明，除玫瑰花的数量和重量在0.2% N + 0.2% P2O5 + 0.2% K2O的紫胶泥处理外，富0.2% N + 0.2% K2O紫胶泥处理的菊花和玫瑰花的数量和重量最高，且显著优于其他处理。施用富含0.2% N + 0.2% P2O5 + 0.2% K2O的紫胶泥，与常规施肥(施用蚯蚓堆肥)相比，菊花的花数和花重分别增加47.4%和38.5%，月季的花重增加25.5%和31.7%。因此，在节省无机肥料和改善土壤肥力状况的同时，应用紫胶泥进行养花施肥可以为紫胶加工厂提供另一个多元化的维度。
