A field experiment was conducted on clay textured soil during Kharif season of 2013 to study the effect of soil amendments and organic foliar sprays on crop growth, seed yield and quality of green gram (Vigna radiata L.). The soil application of organic manures and liquid organic foliar sprays at flower initiation and 15 days after flowering (DAF) significantly enhanced the seed yield and seed quality parameters of green gram. Application of FYM (1/3)+ Vermicompost (1/3) + glyricidia leaf manure (1/3) equivalent to 100% RDP and foliar spray of panchagavya (3%) at flower initiation and 15 DAF recorded significantly more number of pods per plant (21.27), pod length (10.25 cm), number of seeds per pod (12.10), seed yield (12.89 g/plant) and seed yield (1263.68 kg/ha) with concomitant higher seed quality parameters like 100 seed weight (5.86 g), seed germination percentage (95.67 %), shoot length(16.53cm) root length (18.25 cm), seedling vigour index (3308) and protein content (23.79 %) as compared to other treatment combinations and control.

Porous structure of the super absorbent polymer (SAP) was synthesized through inverse suspension method by adding acrylic acid (AA) and acrylic amide (AM) as monomer,N,N'-Methylene-bis-acrylamide (MBA) as cross-linking agent, the mixed solution of methanol and ethanol as pore-foaming agent. The factors that influenced the bibulous performance of the super absorbent polymer were studied including the dosage of cross-linking agent, the dosage of pore-foaming agent, monomer ratio, revolving speed. The Internal structure and surface morphology of SAP was characterized by scanning electron microscopy (SEM). It indicated that when the monomer ratio wasm(AM):m(AA)=1:2; the weight rate of cross-linking agent and pore-foaming agent were 0.06%(compared with the quality of the monomer) and 9%, the product attained the best water absorbency of 2909 g/g in distilled water, the saline absorbency was 124.5 g/g; the water absorption rate was 10. Meanwhile, SEM showed that the structure of the copolymer was full of holes.

Background: Weeds are primary factors that adversely affect growth, yield and seed quality of summer green gram, which can be minimized with adoption of proper weed management practices. This field experiment was conducted to find out the effective weed management practice in summer green gram (Vigna radiata) under zero tillage condition. Methods: In this field-laboratory investigation conducted during summer season 2019 on different herbicides were applied to manage weeds in summer green gram. Eight treatments were applied based on various application windows. In the field and laboratory, the collected samples were determined for growth parameters, nutrient uptakes, seed yield and seed quality of summer green gram. Result: The result revealed that weed free treatment recorded higher growth parameters like, plant height, number of branch/plant, number of leaves/plant and root biomass which was statically at par with Shaked (Propaquizafop + Imezathyper) as post-emergence (POE) at 20 DAS and Pendimethalin as pre-emergence (PE) followed by one hand weeding 20 DAS. Same trends were also observed in seed yield, nutrient content and uptake by seeds. Seed quality parameters like germination per cent (98.00), shoot (25.63 cm) root (14.20 cm) and seedling length (39.83 cm), seedling dry weight (0.16 g), vigour index I (3903.33) and vigour index II (14.96) was higher under weed free followed by Shaked (Propaquizafop + Imezathyper) and Pendimethalin as (PE followed by one hand weeding 20 DAS over weed check.

The formation of effective nodules by rhizobial strains is influenced by both the host and the environment (Gibson, 1977). The interaction between host genotype and strains of Rhizobium sp. has already been established for some species (Gasser et al. 1972; Rai & Singh, 1979). The present study presents data for the contribution of different rhizobial strains to nodulation character and quality of green gram.

Global demand for pulses such as the mung bean has grown in the last years. For successful production of these crops it is necessary to use high quality seeds. Methodologies based on X-ray image analysis have been used as a complementary tool to evaluate the physical quality of seeds due to their speed and potential for automation. The aim of this study was to evaluate the efficiency of X-ray analysis for non-destructive evaluation of the physical quality of Vigna radiata seeds and to relate the variables obtained with their physiological potential. For this, seeds from eight lots were X-rayed and subsequently subject to germination test. In total, 18 physical and physiological parameters were determined. The X-ray image analysis was efficient for evaluating the internal morphology of Vigna radiata seeds and allowed the identification of various damage types. However, it was not possible to relate the physical variables to the seed quality as the lots presented similar germination percentage. Physical variables such as solidity and circularity are related to percentage of root protrusion and length of seedling hypocotyl. Low relative densities indicate deteriorated tissues, related to severe morphological damage and non-viable seeds.
