Background: Groundnut is one of the most important oilseed crops of India. Improving productivity of groundnut to meet the domestic vegetable oil demand through balanced fertilization is the prime challenge lying before the agronomists in the country. With the aim of evaluating phosphogypsum as a source of sulphur nutrition in groundnut, a field experiment entitled “Response of groundnut (Arachis hypogaea L.) to different levels and time of phosphogypsum nutrition” was conducted at Agronomy field unit, University of Agricultural Sciences Bangalore, during kharif-2019. Methods: Experiment was laid out in randomised complete block design (RCBD) with eleven treatments, of which eight have different combinations of phosphogypsum applied as basal and in split (30 DAS) and one with gypsum as basal alone. Whereas, the remaining two treatments, without any additional source of sulphur are included for comparison. Result: Among eleven treatments, application of phosphogypsum @ 125 kg S eq ha-1 in split recorded highest yield attributes, pod yield (2063 kg ha-1), kernel yield (1418 kg ha-1) and sulphur uptake (11.33 kg ha-1). Which were on par with 100 kg S eq ha-1 in split (2014, 1380 and 10.39 kg ha-1, respectively). All other treatments recorded lower values with lowest in treatments without any additional sulphur source.

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.

The effects of photoperiod on reproductive development and yield of two Virginia, one Spanish and one Valencia peanut (Arachis hypogaea L.) cultivar were investigated in the field at Kingaroy, Australia. The objective was to assess the importance of photoperiod as a limitation to post-flowering reproductive development in a cool subtropical environment. A total of five experimental sowings were made between the 1986/87 and 1988/89 growing seasons. Treatments consisted of either natural photoperiods (ranging from 11 to 14 h, depending on sowing date and growth stage) or long (16 h) photoperiods during a range of phenological stages, both pre- and post-flowering. Long photoperiods were achieved by using low intensity light from incandescent bulbs with equal extension periods in both morning and evening. Different sowing dates and seasons were used to produce a range of natural photoperiods, radiation and temperature regimes, while shadecloth was used to alter incident irradiance during the 1988/89 experiments. Photoperiod responses were significant in only one experiment (S2, 1986/87), and were due to effects of treatment during the immediate post-flowering period. Numbers of flowers, pegs and pods were reduced under long photoperiods in cv. Robut 33-1, and to a lesser extent, in cv. White Spanish. The Virginia cv. Uf 781 14-5 was unaffected. The effects of long photoperiods during this 30 day post-flowering treatment were not expressed until after the treatment period. Effects were relatively small and reproductive (pod) yields at maturity were not significantly reduced. The lack of strong photoperiod responses in the reportedly sensitive Valencia cv. NC17090 and the occurrence of the strongest response in the relatively insensitive cv. Robut 33-1 were unexpected. Analysis of climatic data from these experiments, and others reported in the literature, suggested interactions between photoperiod and temperature, with photoperiod effects being only significant at higher temperatures, i.e. in our studies, when mean daily temperature during the treatment period was 26-0�C. This finding is of considerable significance in assessing the importance of photoperiod sensitivity for cultivar adaptation to long day/subtropical environments. A subsequent paper in this series examines photoperiod x temperature interactions more closely under controlled environment conditions.

The present investigation entitled “Effect of sowing dates and establishment methods on growth and yield of kharif groundnut (Arachis hypogaea L.) under lateritic soil” was conducted at Agronomy Farm, Department of Agronomy, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.) during kharif season of 2015. The results revealed that, groundnut crop sown in 23rd MW with broad bed furrow method of sowing produced higher growth and yield attributes as compared to other sowing dates and establishment methods respectively. The crop sown in 23rd MW recorded highest kernel (17.25 q ha-1) and haulm (40.25 q ha-1) yield over remaining sowing dates also broad bed furrow method of sowing produced highest kernel (16.81 q ha-1) and haulm (38.86 q ha-1) yield as compared to flatbed method of sowing.

An experiment was conducted during Kharif seasons of 2009 and 2010 on groundnut (Arachis hypogaea L.) under western dry zone of India following a split-plot design with four dates of sowing (April 20, May 15, June 9 and July 4) and two varieties (HNG 10 and TG 37A) in main- plot and four fertility levels (0, 20 N : 40 P2O5, 30 N : 60 P2O5 and 40 N : 80 P2O5 kg /ha) in sub-plot. Yield component of semispreading variety ‘HNG 10’ i.e. pods/plant, number of kernel/pod, seed index, shelling percentage and yields i.e. pod, kernel, haulm and biological yield were statistically at par with each other from April 20 to June 9 sowing and minimum yield was observed in July 4 sowing, while days to maturity reduced significantly with delay sowing. Variety ‘TG 37A’ sown at July 4 had significantly higher yield attributes and yields than earlier sowing. Harvest index in both the varieties was observed significantly higher in July 4 sowing. Significantly higher yield components and yields were recorded in 30 kg N-60 kg P2O5/ha which was statistically at par with 40 kg N-80 kg P2O5/ha. On the basis of economics, June 9 sowing variety ‘HNG 10’ of groundnut recorded significantly higher net return. DOI: http://dx.doi.org/10.3329/bjb.v43i2.21669 Bangladesh J.
