“…This may be due to its roles mentioned on earlier for improving these parameters and offset of the 'hidden hunger' for GA by its presowing seed treatment or foliar application. Similar results were also obtained by [65][66][67] on pre-sowing seed treatment and by those mentioned on foliar application of GA. The improvement in pods per plant, seeds per pod and 100-seed weight of chickpea cultivar DCP 92-3 grown with the recommended basal dose of N and P, due to foliar application of a small quantity of P and /or S alone or in combination with the soaking and /or spray of GA over the respective control is not far to seek.…”

An experiment was carried out with an aim to enhance the performance of chickpea by the spray of a small quantity of phosphorus (P) and/or sulphur (S) with or without the soaking of GA treatment (10 -6 M GA for 8h) and/ or the GA spray treatment (10 -6 M GA at 60-70 DAS). P and S each at 2 kg/ha were sprayed in two equal splits i.e. half at 60 and the remaining half at the 70 DAS alone or in combination with the GA treatment. Prior to sowing, total seeds of chickpea were grouped into two; one group of seeds was soaked in 0M GA (control) and the other group were soaked in 10 -6 M GA aqueous solution, each for 8 hours. There were total sixteen treatments with ten combinations of P and/or S with GA are possible viz., F PS , S GA + F P , S GA + F S , S GA + F PS , F GAP , F GAS , F GAPS, S GA + F GAP , S GA + F GAS and S GA +F GAPS . The combined application of P and S with GA showed better responses and further improvement in carbonic anhydrase (CA) activity, stomatal conductance (gs), net photosynthetic rate (P N ), nitrate reductase activity (NR), and leghemoglobin content (Lb) at two sampling stages (90 and 100 DAS). This treatment also increased pod number per plant, seed yield per plant and harvest index (HI), seed protein and carbohydrate content at harvest. This combination augmented the protein content (21%), carbohydrate content (11%), seed yield (86%) and HI (91.78%).

“…S also helps in chlorophyll formation [63,64] and stimulates root growth [65]. Thus, being important essential nutrients, P and S are directly or indirectly involved in growth of chickpea like other crops through the production of metabolic compounds.…”

“…Atmospheric S, together with that in superphosphate and ammonium suiphate has generally been considered sufficient for crops. However, there has been a shift towards the use of high-analysis fertilizers containing less sulphur so that one must be on one's gard against further neglect of sulphur in deficient regions 21 In earlier agronomic investigations, those areas in which S application gave increases in crop yie]d and recovery from symptoms were classified as suiphur deficient, but few plant analyses were made 37. Occasionally, total-S was de-termined, but data on S aloiie are not enough to asses the sulphur status since the amount required is proportional, not to the weight of the plant, but to the amount of organic nitrogeiious substaiice, mainly protein, to which the S contributes in a Iixed proportioii.…”

RESUMOO trabalho teve como objetivo estudar alguns aspectos da nutrição mineral do espinafre (Tetragonia expansa Murr.) no que concerne:1 -Efeitos da omissão dos macronutrientes e do boro, na obtenção de um quadro sintomatológico; 2 -Efeitos das carências na produção de matéria seca e composição química da planta.Mudas com trinta dias de idade foram transplantadas para soluções nutritivas carentes nos macronutrientes e/ou em boro. A coleta das plantas foi realizada quando os sintomas de deficiência se tornaram evidentes. No material seco procedeu-se a análise química. Os dados mostram que:1 -os sintomas visuais de deficiência de Ν, K, Ca e Β apresentam-se bem definidos; sendo que os de P, Mg e S são de difícil caracterização ; 2 -os teores dos nutrientes em plantas sadias e deficientes são: * Entregue para publicação em 28/7/1975. Parte da dissertação apresentada pelo primeiro autor para obtenção do grau de Mestre pela USP. Apresentado no I Congresso da Sociedade de Olericultura do Brasil, 20 a 26/7/75,
