A field experiment on deep black soils during rabi season of 2014-15 to study the influence of ferti-fortification on dry matter production, yield and yield components viz., number of pods plant-1, pod weight, 100 kernel weight and shelling percentage of groundnut genotypes. Among groundnut genotypes, ICGV-00351 recorded significantly higher pod, kernel and haulm yield (2656, 1934 and 2894 kg ha-1, respectively), dry matter production at harvest (36.54 g plant-1), number of pods plant-1 (33.66), pod weight (31.81 g plant-1), 100 kernel weight (31.59 g) and shelling percentage (72.77 %) as compared to other genotypes. Among micronutrients application, higher dry matter production at harvest (43.60 g plant-1), pod, kernel and haulm yield (2789, 2051 and 3080 kg ha-1, respectively), number of pods plant-1 (34.08), pod weight (32.25 g plant-1), 100 kernel weight (31.61 g) and shelling percentage (73.21 %) recorded with soil (25 kg ha-1) and foliar (0.5 %) application of ZnSO4 (S4) as compared to control.

Abstract Growth and NPK uptake of peanut of cultivar Shulamit (Arachis hypogaea L.) grown in a sandy soil (Xeropsamment - Torripsamment) was investigated under favorable semi-arid conditions conducive to high yields. The rate of dry matter production was slow until flowering at 44 days after planting when only 6% of the total dry matter had been produced. From flowering until 111 days. 58% of the total dry matter was produced with an average rate of 97 kg DM ha-1 day-1. Thereafter, from 112 days until 128 days, at the pod ripening stage, the rate was 233 kg DM ha-1 day-1. Total dry matter production was 11,200 kg ha-1, of which 54% was in the leaves and stems and 46% in the pods. The pod dry matter yield was 5200 kg ha-1. The total uptake of N and P followed generally that of dry matter production, whereas highest K uptake occurred at 128 days and then decreased by 26% at harvest time. The total uptake of N, P, and K was 300, 27 and 244 kg ha-1, respectively. At 128 days the N, P, and K in the pods was 63, 71, and 16% of the total uptake of N, P, and K, respectively.

Groundnut (Arachis hypogaea L.) is one of the world’s most popular oilseed crops. Nut yield in groundnut is polygenically controlled and is influenced by its component characters. A field experiment was conducted to study the variation in respect of kernel yield and its component characters along with dry matter production and partitioning at important vegetative and reproductive growth stages in nineteen genotypes of groundnut. The correlation studies were also conducted to prioritize morphological and physiological traits for improving yield. Genotypes exhibited significant differences among them in respect of kernel yield and its all attributes. Highly significant differences were recorded in respect of dry matter production and partitioning to different plant parts at pre-anthesis (30 DAS) and post-anthesis pod filling (60 DAS) stages.

During the rainy season in India, bamboo screens intercepting approximately 46% of the incident light were used to simulate the effect of shading by a cereal grown as an intercrop with groundnut (Arachis hypogaea L.). The treatments comprised an unshaded control and two durations of shading extending from peg initiation (T1) and the onset of pod filling (T2) to final harvest. Plant height was greatest in the T1 crop, but the maximum rates of leaf development on the main stem, leaf area expansion and pod production were similar in all crops. Shading appeared to reduce the rate of the linear growth phase because the reduced light interception was not entirely offset by an increase in light-use efficiency. Premature senescence in the shaded crops coincided with the virtual cessation of pod production, although continued allocation of dry matter to reproductive structures in the T1 crop resulted in a greater proportion of pods being filled at final harvest than in the other treatments. The responses of groundnut to timing of shade are discussed in terms of their implications for the selection of improved crop combinations for intercropping.

On sandy soil of low K availability, permanent pasture cut 5 times during the year received up to 200 kg/ha K2O as 40% KC1 before or after one of the cuts. The effect of K fertilizing in autumn depended largely on K withdrawal with previous cuts. K uptake was not determined by growth. Except for the first cut K uptake was greater than that needed for reasonable growth. No effect of temperature on K response was found. The best treatment was 200 kg/ha K2O applied in spring.
