The experiment was conducted at lowland series of wet lands, International Rice Research Institute (IRRI) Farm, Los Banos, Laguna, Philippines. The rice variety PSBRc 82 was raised during wet season (June – October), and the experiment was laid out in randomized block design with four replications. There were eleven treatments viz., control, recommended NPK fertilizer, -N, -P, -K, LCC 3, LCC 4,...

The field experiment was carried out during Khairf 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P), to study the “effect phosphorus and micronutrients on yield economics rice (Oryza sativa L.)”. laid in Randomized Block Design with ten treatments including control each replicated thrice. Significantly higher grain (6.20 t/ha) straw (8.37 were recorded treatment 9 app...

Pre-seeding tillage of long-term no-till soil may alter soil quality by changing some properties, but the magnitude of change depends on soil type and climatic conditions. Effects of short-term (2 or 3 years) tillage (hereafter called reverse tillage [RT]) of land previously under long-term no-till (NT, 29 or 30 years), with straw management (straw removed [SRem] and straw retained [SRet]) and ...

Aims: To study the phosphorus requirement of Rice - zero till maize (Zea mays L.) cropping system on productivity and soil available Phosphorus balance. Study Design: Randomized block design (two factors). Methodology: The field experiment was conducted for two consecutive years at College Agriculture, Rajendranagar, Hyderabad. Levels P2O5 (kg ha-1) applied to rice (5 levels) (3 respectively we...

At the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P.), India, a field experiment was carried out during Harvest season 2022. To investigate how spacing and nitrogen affect sorghum growth fodder production (Sorghum bicolor L.). The treatments include at rates 60, 80, 100 kg/ha, spaced 35...

Grazing systems may alter botanical composition and productivity of grasslands through differential use in time, space, or intensity. Seven simulated grazing treatments were applied six years in eastern Montana, USA to determine effects on plant community composition and standing crop. Treatments were moderate stocking (28.8 AUD ha 1 year ) of cattle using 3-pasture summer rotation, season-long...

A field study was conducted in a semi-arid climate to assess the effect of nitrogen and phosphorus on timely sown bed planted wheat under varying irrigation levels. The soil sandy loam, having 0.36% organic carbon pH 8.2. It low available N (132 kg/ha), medium P (11.6 kg/ha) rich K (325 kg/ha). experiment consisted sixteen treatment combinations four levels (Two, three, five irrigations) main p...

We compared th...

The field experiment was conducted during Rabi season, 2021 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P) under sandy loam soil conditions. laid out in Randomized Block Design with nine treatments each replicated thrice comprising three levels Zinc (6, 8 and 10 kg/ha) sulphur (20 kg S/ha, 40 S/ha 60 S/ha). results showed that the growth par...

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...
