Abstract

A thrice replicated field experiment was conducted to study the effect of biocompost and inorganic fertilizers on yield and quality of potato. The experimental results revealed that, highest tuber yield was recorded in 100% NPK followed by 87.5% NPK with the least in control. Application effect of biocompost @ 12 t ha^-1 was found to be similar to 50% NPK in respect of potato yield, while the application of inorganic fertilizers above 50% NPK showed superiority in terms of yield over all the doses of biocompost. Among the various treatments of inorganic fertilizers and biocompost, treatment where 100% RDF of NPK was applied proved to be superior to other treatments in terms of growth parameters, tuber yield and macronutrients content. However, micronutrient content in tuber was found higher in the treatments of biocompost application. By comparing the tuber yields obtained in the different treatments at harvesting, it was found that 50% inorganic NPK can be saved with the application of biocompost @ 12 t ha^-1. Micronutrients content in soil was buffered to its initial value with the application of different doses of biocompost while declined in case of inorganic fertilization.

Abstract

It is imperative that the world farmlands turn out to be the frontline for the battle to feed the projected 9 billion population globally. The deleterious effects of climate change on food security can be counteracting by broad-based agriculture development particularly enhanced crop diversification to mitigate farmer risk about complete destruction of crop that will overcome the impacts of climate change. It will also lead to benefits like improved food security besides improving soil nutrients. Therefore, a field trial was conducted. The experimental results revealed that application of 100% NPK with PSB and Zn in paired planted mashbean accumulated significantly more dry matter than rest of the treatment combinations, whereas normal planted mashbean intercropped with maize recorded maximum total uptake (8.15%) than 100% NPK alone. Likewise in maize similar trends were observed in dry matter and protein content. Moreover, application of 100% NPK alone with PSB and Zn on normal planted sole maize was brought significant improvement in organic carbon and potassium. However, nitrogen recorded higher under paired planted maize+mashbean. Though, normal (50 cm) planted maize+mashbean resulted significantly higher B:C ratio (2.73) at same fertility level.

Abstract

A field experiment was conducted during kharif season of 2013 on sandy loam soil. The experiment aimed to evaluate the performance of hybrid maize with urdbean and mungbean under different planting patterns. In this investigation, 9 treatment combinations viz., maize with normal (1:1), paired (2:2) and strip (3:3) planted urdbean (Vigna mungo) and mungbean (Vigna radiata) along with all the three crops in their sole stands were tested in randomized block design with 3 replications. The study revealed that strip planted maize+urdbean (3:3) being on par with maize+mungbean (3:3) recorded significantly highest values of growth parameters, nodulation habitat, yield attributes and yield of maize in terms of grain yield (45.6 q/ha) and stover yield (77.8 q/ha), except phenological parameters and mortality %. In terms of protein in maize grains and nitrogen, phosphorus and potassium content in grains and stover, strip (3:3) planted maize proved its superiority over sole and normal (1:1) planted maize. Likewise, in intercrops, all the growth parameters, yields, nutrients content and protein yield were statistically superior in their sole as compared to normal (1:1), paired (2:2) and strip (3:3) planting with maize, except plant height.
