A field experiment was conducted during 2021-22 to evaluate the influence of POLY4 on growth and yield of mustard
under various doses of nutrients with POLY4 fertilizerlevels on production and soil health.The experiment was laid out
in completely randomized block design, comprising various doses of nutrients with POLY4 fertilizer included in 9
treatments (Control; 100% NPS; Farmers practice (60-40-0-10 kg ha-1 NPKS); 100% RDF(120-60-60-40 kg ha-1 NPKS) and
100% K through MOP; 100% RDF(120-60-60-40 kg ha-1 NPKS) and 100% K through POLY4; 100% RDF (50% K by MOP
and 50% K by POLY4); 100% RDF(25% K by MOP and 75% K by POLY4); 100% NPS + 75%K (100% K by POLY4) and
100% NPS + 50% K (100% K by POLY4) replicated three times. Results showed that treatment T7
(100% RDF i.e.25% K
by MOP and 75% K by POLY4) was significantly superior to rest of the treatments with respect to plant height, primary
branches/plant, secondary branches/plant and dry weight. Application of 100%RDF (25% K by MOP and 75% K by
POLY4)was also better over other treatments in respect of yield and yield attributes viz.number of siliquae per plant and
number of seeds etc. in clay loam soils of Bundelkhand region.The mustard crop fertilized with 100% RDF (25% K by
MOP and 75% K by POLY4) fetched the highest net returns with maximum benefit-cost ratio.
