“…Maximum stover yield with KNO3 1 % (F3) foliar spray might be due to better absorption, translocation of nutrients, consequent cellular functions and increased enzyme activities which were reflected in higher values of growth parameters which resulted in higher stover yield. These results are in conformity with Waraich et al [32] Keerthi et al [33] Vijayakumar et al [26] and Laishram et al [27].…”

A field investigation was conducted during two consecutive kharif seasons of 2019-20 and 2020-21 to study the effect of tillage, nutrient levels and foliar sprays on yield and nutrient uptake of redgram on sandy loam soil which was low in available nitrogen, medium in available phosphorus and available potassium. The research was conducted in a split-split plot design, consisting of three tillage practices in main plots, three nutrient levels in sub-plots and three foliar sprays in sub-sub plots. Higher seed yield and nutrient uptake of redgram was recorded with vertical tillage with subsoiler upto 60 cm deep at 1 m interval with application of 125 % RDF and with foliar application of KNO3 1 % twice with 15 days interval at 50 per cent flowering stage.

“…Maximum number of seeds pod -1 and hundred seed weight (Table 2) was recorded with F 3 due to the higher availability of nutrients that was supplied through foliar feeding of KNO 3 which enhanced the number of floral buds, prevented the floral shedding and activate the biochemical functions in plants, enzyme activation, photosynthesis, cell division and translocation of photosynthates from source to sink that resulted in larger pod filling period leading to greater number of seeds pod -1 . Similar results were also reported earlier by Keerthi et al (2015), Gorakshnath et al (2016) and Vijayakumar et al (2019). Control (No spray) (F 1 ) recorded lower number of seeds pod -1 due to poor partitioning efficiency of photosynthates from source to sink.…”

Background: Pigeonpea productivity is low as it is grown in low fertility soils under inadequate fertilizer applications that has led to emergence of several nutrient deficiencies. The lower yield of pigeonpea is not only due to its cultivation in sub marginal lands, but also due to poor management, flower dropping and subsoil compaction that leads to restricted water infiltration, there by bringing many chemical and biological changes which affect the plant growth. It is important to adopt appropriate tillage practices in combination with proper nutrient management practices that avoid degradation of soil structure, reduce flower drop, maintain crop yield as well as ecosystem stability. Methods: A two year field experiment was conducted during two consecutive kharif seasons of 2019-20 and 2020-21 at S.V. Agricultural College, Tirupati Andhra Pradesh to study the effect of different tillage, nutrient management practices and foliar application of KNO3 and borax on yield attributes and yield of pigeonpea [Cajanus cajan (L.)] in a split-split plot design, consisting of three tillage practices in main plots, three nutrient levels in sub plots and three foliar sprays in sub-sub plots on sandy loam soil which was low in available nitrogen, medium in available phosphorus and available potassium. Result: Our investigations concluded that among combinations higher number of pod bearing branches plant-1, number of pods branch-1, total number of pods plant-1, number of seeds pod-1, hundred seed weight and seed yield of pegonpea was recorded with vertical tillage with subsoiler upto 60 cm deep at 1 m interval coupled with application of 125% RDF and with foliar application of KNO3 1% twice with 15 days interval at 50 per cent flowering stage.

“…Crop yield is important in agriculture as it shows the amount of produce harvested per unit area for a given time (Keerthi et al 2015). Seasons provide different weather conditions for the growth and development of different varieties; hence, they can convert resources to outputs in form of yields (Sellami et al 2021).…”

Effects of Variety, Spacing and Nitrogen Application on Chickpea (Cicer arietinum) Growth and Yield in Embu County, Kenya

Chickpea is a pulse crop that is rich in proteins and helps in fulfilling the requirement of protein for vegetarian people thus yield maximization needed. This study aimed to determine the effects of spacing, nitrogen rates, and their interactive effects on the growth and productivity of the selected chickpea varieties. Field experiments were conducted at Mwea, Kenya between 2017 and 2018 involving four varieties (Saina K, Mwanza 2, Chaina I and Chaina III) at a spacing of 50x10cm, 50x20cm, and 50x30cm, and starter nitrogen-fertilizer application rates 0kg, 30kg, 60kg, and 90kg ha-1. A split-split plot design arranged in a 4x3x4 layout was used in the current study. Data related to plant height, biomass, grain yield, and harvest index were collected and subjected to statistical analysis by GLM in SAS 9.4 computer software. Variations occurred in measured traits like the height of crops (34.81-38.00cm), biomass yield (3.31 - 8.08t ha-1), seed yield (0.14 to 1.9t ha-1), and percent harvest index (5 - 45%) was reported. Mwanza 2 expressed the highest plant height, biomass, and grain yield. The highest plant biomass was obtained under 50x10cm spacing, while the highest grain yield weight was reported under 50x30cm spacing x 60kg N ha-1. From the results of the study, it can be concluded that the highest enhanced growth and productivity of chickpea were realized at interactions of Mwanza 2x50x10cmx90kg ha-1 nitrogen rate in the study area.
