during samba (August-December) seasons of 2012 and 2013 to find out the optimum crop geometry, age and number of seedlings on growth and physiological characters in relation to yield of low land rice. The experiment consisted of three mainplot treatments viz., M 1 -25 x 25 cm, M 2 -25 x 20 cm and M 3 -25 x 15 cm and six sub-plot treatments S 1 -14 day old seedlings (DOS)+1 seedling/hill, S 2 -14 DOS+2 seedlings/hill, S 3 -14 DOS+3 seedlings/hill, S 4 -21 DOS+1 seedling/hill, S 5 -21 DOS+2 seedlings/hill and S 6 -21 DOS+3 seedlings/hill and replicated thrice in a split plot design. The treatment combination of M 3 S 5 (25 x 15 cm spacing and 21 DOS with two seedlings hill -1 ) recorded higher nitrogen uptake than others at panicle initiation, flowering and harvest stages. The same trend was followed on phosphorus and potassium also.

“…In fact, vermicompost offers favorable conditions for soil microbes that are involved in nutrient transformation and, as a consequence, availability and retention capacity of nutrients are enhanced, which results in higher nutrient uptake and use efficiency in rice. The impact of vermicompost on the improvement of nutrient uptake was reported by some researchers [90,95,96]. The organic acids released from vermicompost solubilize nutrients from complexes during decomposition, decrease adsorption capacity and increase desorption of nutrients in soil, supporting higher nutrient uptake in vermicompost treatment [97,98].…”

Although its mechanism of action, particularly under wetland condition, is not clearly understood, vermicompost, a good source of humus and plant nutrients, has been used as organic manure in many parts of the world in order to increase crop production. Here, an anaerobic incubation study and a field study were conducted to observe the nutrient release pattern from vermicompost and its influence on performance and nutrient uptake in wetland rice. Two contrasting soils, viz. highly weathered terrace soil and very young floodplain soil, were subjected to anaerobic incubation, while the field trial was conducted in the terrace soil with control (no amendments), mineral fertilizer, vermicompost (10 t ha−1) + mineral fertilizer, cow dung (10 t ha−1) + mineral fertilizer, vermicompost (20 t ha−1) + mineral fertilizer and vermicompost (local farmer’s practice) + mineral fertilizer treatments. Results showed that there were significant increases in nitrogen (N) and phosphorous (P) release in floodplain soil but not in terrace soil, suggesting that nutrient release from vermicompost is soil-dependent. The performance of Boro rice in terms of yield and yield attributes improved significantly in the case of the integrated application of vermicompost with mineral fertilizer. Specifically, combined application of mineral nutrients and vermicompost (10 t ha−1) significantly increased grain yield by 25% compared to the control treatment. We believe that this occurred due to an improvement in supply and subsequent uptake of nutrients, especially N and P. Altogether, our results suggest that vermicompost could increase crop performance under field conditions, and, although these effects may not be significant in short-term incubation studies, they may be even larger in floodplain soil.

“…During both the years of investigation significantly highest protein content was achieved in the treatment where RDNK+ Dhaincha @ 10 t ha -1 (M3-20.40 and 21.56%). However, this treatment was on par with RDNK+ sunhemp @ 10 t ha -1 (M2-19.96 and 20.88%), however these two treatments were significantly superior over RDNK+ FYM @ 5 t ha - [15] reported that highest protein were registered with addition of organic manures along with inorganic fertilizer might be due to protein content is dependent on N content of grain thereby increased the protein synthesis under adequate supply of nitrogen [16][17][18].…”

A field experiment was conducted on phosphorus dynamics in relation to nutrient management in rice- blackgram cropping sequence with respect to yield and quality as influenced by effect of organic manures and inorganic phosphorus at Agricultural College Farm, Bapatla. The results revealed that grain yield of rice was significantly higher with the application of 100% RDNK in combination with Dhaincha @10t ha-1 (M3) and it was on par with that of application of RDNK along with sunhemp @10t ha-1 (M2). However significantly lower was recorded in RDNK alone (M0) during both the years of the study. Among the P levels, the treatment P5 (120 kg P2O5 ha-1) recorded significantly highest grain yield and it was on par with P4 (90 kg P2O5 ha-1) and P3 (60 kg P2O5 ha-1) and lowest was recorded in P1 (0 kg P2O5 ha-1). In succeeding blackgram seed yield was significantly influenced by the organic manures and phosphorus levels imposed to preceding rice crop. The seed yield was significantly higher with the application of 100% RDNK in combination with Dhaincha @10t ha-1 (M3) and it was on par with that of application of RDNK along with sunhemp @10t ha-1 (M2) and RDNK+ FYM @ 5t ha-1 (M1). However significantly lower was recorded in RDNK alone (M0) during both the years of the study. Among the P levels, the treatment P4 (90 kg P2O5 ha-1) recorded significantly highest seed yield and it was on par with P5 (120 kg P2O5 ha-1), P3 (60 kg P2O5 ha-1) and P2 (30 kg P2O5 ha-1), while lowest was recorded in P1 (0 kg P2O5 ha-1). Regarding quality parameters of rice grain viz., amylose and protein were recoeded significantly higher in RDNK+Dhaincha @10t ha-1 (M3) and this was on par with that of application of RDNK along with sunhemp @10t ha-1 (M2), while M2 was remain on par with RDNK+ FYM @ 5t ha-1 (M1). Among the P levels, the treatment P5 (23.86 and 24.71%) registered significantly higher amylose content and lower was registered in P1 (21.59 and 22.43%). However, protein content was slightly increased from 0 to 120 kg P2O5 ha-1 but not significantly differed. Similarly the data regarding influence of organics and P levels applied to preceeding rice crop on protein content of succeeding blackgram followed same trend as in rice.
