A field experiment was carried out during rainy (Kharif) season of 2019-20 at the research farm of AKS University, Satna, Sherganj, Madhya Pradesh. The treatments comprised twelve mechanical and chemical weed control treatment as detailed in chapter III. The experiment was laid out in randomized block design with three replications. An uniform dose of 25 kg N and 50 kg P2O5 and 25 kg K2O/ha was applied through urea, SSP and MOP, to all the experimental plots. Moongbean var. Shikha was sown on 13 July, 2019 keeping a seed rate of 25 kg/ha and row spacing of 30 cm. The plant to plant spacing of 10 cm was maintained by thinning. The weedicides were applied with or without hand weeding once or twice as per treatments. The crop was harvested on 17-23 September, 2019. Amongst the mechanical and chemical weed control method (IWM), hand weeding twice (weed-free condition) proved the best which enhanced significantly higher growth, yield attributes, yield and seed protein of green gram. The seed yield was up to 0.80 t/ha, net income up to Rs.29805 /ha and seed protein 24.46 %. Thereafter each of the herbicides applied along with hand hoeing proved for better than herbicide applied alone. Quizalofop-p-ethyl 700 g/ha with hand hoeing proved better than other three herbicide with hand hoeing. Therefore looking to the labour problem for hand weeding quizalofop + hand hoeing may be adopted to gain maximum benefit from green gram.
在2019- 2020年雨季(Kharif)期间，在中央邦Sherganj的Satna AKS大学研究农场进行了田间试验。处理包括12种机械和化学除草处理，详见第三章。试验采用随机区组设计，设3个重复。所有试验田均通过尿素、SSP和MOP施用25 kg N、50 kg P2O5和25 kg K2O/ha。月豆品种Shikha于2019年7月13日播种，播种率为25公斤/公顷，行距为30厘米。通过间伐保持植株间距10 cm。每个处理分别用手除草或不用手除草一次或两次。该作物于2019年9月17日至23日收获。在机械和化学除草方法中，手除草2次(无草条件)效果最好，能显著提高绿克的生长、产量属性、产量和种子蛋白。种子产量可达0.80 t/ha，净收入可达29805卢比/ha，种子蛋白含量为24.46%。此后，每一种除草剂与手锄配合使用，证明比单独使用除草剂效果更好。700 g/ hm2手锄除草剂比其他3种手锄除草剂效果更好。因此，考虑到手工除草的劳动力问题，可以采用手动除草+手动锄地的方法，以获得最大的绿克效益。

From many years, global cotton production suffers from waterlogging stress. Climatic variation and heavy rainfall conditions with poor internal soil drainage mechanism limits the growth and development of cotton crop due to waterlogging. It reduced the soil oxygen which causes the severe yield losses and sometimes even failure of a crop. Indeterminate growth habit of cotton plant makes it able to adapt this stress by activation of the escape, self compensation and quiescence mechanism. The reduction of biomass, development of adventitious roots and accelerated growth mechanism, all are associated with adaption and tolerance mechanisms. Waterlogging significantly affect the cellulose and sucrose content of fiber in cotton. Sodic soils also exacerbate the waterlogging stress because these soils already suffer by aeration stress. Different growth stages are effect differently but flowering and boll setting stage is more sensitive to waterlogging conditions.

The effect of introgression of the temperate maize population BUGARD on the grain yield of a low-yielding tropical maize population well appreciated for the quality of its grains, NCP80, was studied. NCP80 was crossed with BUGARD to obtain the F1. The BC1 obtained by backcrossing the F1 to NCP80 was random mated thrice. The tropical parent NCP80 and the BC1 (NBN) were evaluated in two tropical locations using a randomized complete block design with three replications. Introgression of the temperate population BUGARD into the tropical population NCP80 significantly increased grain yield. The resulting population, NBN, appeared, moreover, significantly earlier than NCP80 and not significantly different from it for resistance to rust, tropical blight and maize streak, ear height, husk cover and harvest index. NBN may, further, be improved for resistance to maize streak and grain yield by recurrent selection.

The Generalized Logarithmic Series Distribution (GLSD) adds an extra parameter to the usual logarithmic series distribution and was introduced by Jain and Gupta (1973). This distribution has found applications in various fields. The estimation of parameters of generalized logarithmic series distribution was studied by the methods of maximum likelihood, moments, minimum chi square and weighted discrepancies. The GLSD was fitted to counts of red mites on apple leaves and it was observed that all the estimation techniques perform well in estimating the parameters of generalized logarithmic series distribution but with varying degree of non-significance.

A field experiment was conducted during kharif season, 2018 and 2019 at S.V. Agricultural college, Tirupati to study the ‘Variation in reproductive efficiency of groundnut (Arachis hypogea L.) genotypes at different planting densities’. Instant increase in groundnut yields can be achived by reorienting its planting geometry. However identification of right variety with right plant architechture which fits into closed spacings is reduced. The experiment was laid out in split plot design with twelve treatments and three groundnut varities Kadiri 6, Kadiri 9 and Dharani with four spacings (S1: 30X10 cm, S2: 30X5 cm, S3: 20X10 cm and S4: 20X5 cm). Among the Spacings 20X10 cm (50 plants m-2) recorded significantly higher (3,616.87 kg ha-1) followed by 20x5cm (3,157.07 kg ha-1) and significantly lower pod yields in 30x10 cm (2,904.87 kg ha-1) and recommended spacing 30X5cm (2,540.07 kg ha-1). Among the three varieties Decumbent-3, Dharani recorded highest pod yield (3403.48 kg ha-1) followed by Decumbent-2 type, kadiri-9 (3292.65 kg ha-1) and least by Erect type, Kadiri-6 (2467.94 kg ha-1). However genotype performance was varied with the spacings adopted Kadiri-6 performed better under recommended spacing only (30x10 cm). Kadiri-9 variety also showed decreased yields when plant to plant to plant spacing was reduced. However Dharani recorded higher flower to peg ratio, peg to pod ratio and yields even in plant to plant and row to row spacings were reduced. Hence, to increase the groundnut productivity Dharani can be recommended at a spacing of 20x10 cm (50 plants m-2).
为研究花生(arachhis hypogea L.)基因型在不同种植密度下繁殖效率的变化，于2018年和2019年在蒂鲁帕蒂S.V.农学院进行了田间试验。通过调整种植的几何形状，可以立即提高花生的产量。然而，对适合封闭间距的正确品种和正确植物结构的识别却减少了。试验采用分畦设计，12个处理，选用卡迪里6号、卡迪里9号和达拉尼3个花生品种，4个间距(S1: 30X10 cm、S2: 30X5 cm、S3: 20X10 cm和S4: 20X5 cm)。其中，20X10 cm(50株m-2)的荚果产量显著增加(3,616.87 kg ha-1)，其次是20x5cm (3,157.07 kg ha-1)， 30x10 cm (2,904.87 kg ha-1)和推荐间距30X5cm (2,540.07 kg ha-1)的荚果产量显著降低。在3个品种中，达兰尼的豆荚产量最高(3403.48 kg ha-1)，其次是康2型卡迪里9号(3292.65 kg ha-1)，直立型卡迪里6号最低(2467.94 kg ha-1)。但基因型表现随株距的不同而不同，Kadiri-6在推荐株距(30 × 10 cm)下表现较好。Kadiri-9品种在株距减小时也表现出产量下降的趋势。然而，达拉尼记录了更高的花与钉比、钉与荚比和产量，甚至在植株与植株和行与行间距上也有所减少。因此，为了提高花生产量，可以推荐在20 × 10厘米(50株m-2)的间距上种植达拉尼。
{"title":"Variation in Reproductive Efficiency of Groundnut (Arachis hypogea L.) Genotypes at Different Planting Densities","authors":"M.

Agricultural college, Tirupati to study the ‘Variation in reproductive efficiency of groundnut (Arachis hypogea L.) genotypes at different planting densities’. Instant increase in groundnut yields can be achived by reorienting its planting geometry. However identification of right variety with right plant architechture which fits into closed spacings is reduced. The experiment was laid out in split plot design with twelve treatments and three groundnut varities Kadiri 6, Kadiri 9 and Dharani with four spacings (S1: 30X10 cm, S2: 30X5 cm, S3: 20X10 cm and S4: 20X5 cm). Among the Spacings 20X10 cm (50 plants m-2) recorded significantly higher (3,616.87 kg ha-1) followed by 20x5cm (3,157.07 kg ha-1) and significantly lower pod yields in 30x10 cm (2,904.87 kg ha-1) and recommended spacing 30X5cm (2,540.07 kg ha-1). Among the three varieties Decumbent-3, Dharani recorded highest pod yield (3403.48 kg ha-1) followed by Decumbent-2 type, kadiri-9 (3292.65 kg ha-1) and least by Erect type, Kadiri-6 (2467.94 kg ha-1). However genotype performance was varied with the spacings adopted Kadiri-6 performed better under recommended spacing only (30x10 cm). Kadiri-9 variety also showed decreased yields when plant to plant to plant spacing was reduced. However Dharani recorded higher flower to peg ratio, peg to pod ratio and yields even in plant to plant and row to row spacings were reduced. Hence, to increase the groundnut productivity Dharani can be recommended at a spacing of 20x10 cm (50 plants m-2).","PeriodicalId":13334,"journal":{"name":"Indian Journal of Pure & Applied Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75089785","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}
