“…Enhancement in soybean growth under minimum tillage with residue treatment might be due the reason that the soil water was conserved and used for soybean growth rather than evaporation. Similar results were found by Sikka et al (2018) in soybean. They reported that plant height tended to increase with the application of wheat straw mulch over no mulch treatment.…”

A field experiment was conducted during kharif season of 2019 at the Research Farm, Department of Agronomy, CSKHPKV, Palampur to study the effect of tillage and fertilizer doses on growth and growth indices of soybean under conservation tillage systems. The experiment consisted of twelve treatment combinations which included three tillage systems minimum tillage, minimum tillage with crop residue and conventional tillage and four fertility levels viz; 25 % recommended dose of fertilizer (RDF) , 50 %(RDF) , 75 % RDF and 100% RDF and which were tested in split plot design with tillage system in main plots and fertility levels in sub plots.The soil texture of experimental site was silty clay loam. Minimum tillage along with crop residues (T2)recorded significantly taller plants and higher dry matter accumulation followed by conventional tillage. Absolute growth rate, crop growth rate, dry matter efficiency, relative growth rate and unit area efficiency were significantly higher with minimum tillage + crop residue treatment. Application of 100 % followed by 75 % recommended dose of fertilizer resulted in significantly higher growth parameters and growth indices.

“…The number of pods/plant and seed yield were found to be significantly highest at the lower seed rate for faba bean and recorded significantly lowest at the highest plant density (Wakweya & Meleta, 2016). Similarly, Sikka et al (2018) reported that the number of pods/plant significantly decreased in soybean at a higher seed rate because of the competition for space, water, sunlight and plant nutrient.…”

Background: Egusi melon production is declining, even though the crop plays a significant role in the well-being of farmers. Few farmers that grow the crop do not allow adequate spacing and seed rate which compels the crop to produce flourishing vegetative parts without producing many fruits. The study was therefore, aimed at determining the effect of planting distance and seed rate on the growth and yield of egusi melon. Methods: A split-plot design which was replicated thrice was adopted to carry out the study during 2018 and 2019 planting seasons. Twenty-four plots were made and were randomly assigned to eight treatment groups with each replicating thrice. The egusi melon seeds were sown in four different seed rates of one seed/hole, two seeds/hole, three seeds/hole and four seeds/hole and four different spacing of 30cm × 50cm, 45cm × 70cm, 60cm × 60cm and 60cm × 90cm respectively. Analysis of variance was used to analyze the data collected and was tested at 0.05 level of probability. Result: The number of leaves/plant, branches/plant, flowers/plant, fruits/plant and fruit weight (g) were significantly higher in egusi melon planted at 60cm × 90cm. Furthermore, the parameters measured were significantly higher in egusi melon planted at 1 seed/hole.

“…However, they concluded that grain accumulation of N, P, K, and S was not influenced by seed rate or spacing. A three year study suggested that the maximum total uptake of nutrients in soybean is under higher seed rate i.e., intense spacing [30].…”

Through the study we aim to explore agronomic intervention to provide nutritional security to growing population, with limited resources and changing climatic conditions. The objective of the study is to investigate the impact of system intensification on nutrient content and nutrient uptake in soybean varieties within ridge and furrow planting system. The experiment was conducted during Kharif 2019 at Pantnagar, India. It was designed in a split-plot layout with eight treatments, replicated thrice. The main plot treatments included two soybean varieties: PS-1092 and SL-958. Four system intensification treatments were within the sub-plots, (plant-to-plant spacing -5 cm, 10 cm, 15 cm, and 20 cm). Nitrogen, Phosphorus, Potassium and Sulfur content in seed was significantly highest at spacing 10 cm as compared to other spacing treatments (P value=.05). Nitrogen, Phosphorus Potassium and Sulfur uptake for both seed and stover was the maximum at plant to plant spacing of 10 cm which was significantly higher than other plant to plant spacing treatments at 5 % level of significance. Intense plant to plant spacing of 10 cm resulted into the significantly higher partial factor productivity (PFP) of nutrients at P=.05. Although nutrient content, nutrient uptake and PFP in soybean is higher at plant to plant spacing of 10 cm, nutrient harvest index is better achieved at wider spacing of 15 to 20 cm. Under no fertilizer limitation, system intensification can be useful to enhance nutrient content of seeds but in cases of limited fertilizer availability wider spacing is more beneficial to achieve higher nutrient use efficiency. Further investigations are needed to fine-tune these practices across diverse geographic regions and soil types. GHG emissions from soybean grown in varying planting geometry needs to be studied.
